This replaces a couple of the MaterialUI icons introduced in #1776 with
their original counterparts in Font Awesome, but wrapped in a MaterialUI
`Icon` tag. Also fix Linkerd logo padding in sidebar.
Part of #1781.

The popover on the src/dst column in the top and tap tables disappeared
before a use could click on it.
Modify the popovers to be reachable, also reimplement them as activated
by mouse clicks rather than mouse over events, allowing the src/dst
column to be both clickable and provide an icon for popover.
Fixes#1784

We make several changes to the service profile spec to make service profiles more ergonomic and to make them more consistent with the destination profile API.
* Allow multiple fields to be simultaneously set on a RequestMatch or ResponseMatch condition. Doing so is equivalent to combining the fields with an "all" condition.
* Rename "responses" to "response_classes"
* Change "IsSuccess" to "is_failure"

Try to squish the metrics columns so that the data fits on the page without
having to scroll the table. This was mostly evident in the Tap and Top tables,
where a lot of the table content would be initially out of view.
This branch also includes an unrelated tiny fix for max error length, which had
been changed from 500 to 50 for testing, and had not been changed back
A container called `proxy-api` runs in the Linkerd2 controller pod. This container listens on port 8086 and serves the proxy-api but does nothing other than forward gRPC requests to the destination container which listens on port 8089.
We remove the proxy-api container altogether and change the destination container to listen on port 8086 instead of 8089. The result is that clients still use the proxy-api by connecting to `proxy-api.<ns>.svc.cluster.local:8086` but the controller has one fewer containers. This results in a simpler system that is easier to reason about.

Service profiles must be named in the form `"<service>.<namespace>"`. This is inconsistent with the fully normalized domain name that the proxy sends to the controller. It also does not permit creating service profiles for non-Kubernetes services.
We switch to requiring that service profiles must be named with the FQDN of their service. For Kubernetes services, this is `"<service>.<namespace>.svc.cluster.local"`.
This change alone is not sufficient for allowing service profile for non-Kubernetes services because the k8s resolver will ignore any DNS names which are not Kubernetes services. Further refactoring of the resolver will be required to allow looking up non-Kubernetes service profiles in Kuberenetes.

The existence of an invalid service profile causes `linkerd check` to fail. This means that it is not possible to open the Linkerd dashboard with the `linkerd dashboard` command. While service profile validation is useful, it should not lock users out.
Add the ability to designate health checks as warnings. A failed warning health check will display a warning output in `linkerd check` but will not affect the overall success of the command. Switch the service profile validation to be a warning.

This branch:
- adds a "meshed" badge to the namespace overview page instead
of a green checkmark (uses Chip)
- fixes aforementioned meshed indicator not showing up in firefox
- vertically centers the ( ! ) icons in the metrics tables
- vertically centers the dots in the metrics tables
Try to standardize theming and colours throughout the app:
- Move Material UI theme definition into its own file
- Use theme colours in success rate charts
- Remove all colour definitions from styles.css
- Remove unused styles in styles.css
- Audit bare h tag usage throughout the app; replace with Typography
- Standardize the colours to the theme for Progress.jsx
- Use theme colour in Spinner
- Default to warning in meshed status table bar chart
The `proxy-api` service included a stub implementation of `GetProfile`
instead of forwarding requests to the `destination` service.
This change fills in the proxy-api service's `GetProfile` implementation
to forward requests to the destination service.
This branch includes some small appearance tweaks for tables in the app.
- Removes the restrictions on the MetricsTables for Authorities Grafana
links (Authorities Grafana dashboards were added in #1772)
- Fixes the tables overflowing their containers on the Overview page
- Allows tables to be denser, allowing for more data on screen
- Fixes the colour of the meshed status bar in the ServiceMesh page
- Rixes the ErrorModal icon alignment and colour
- Small appearance tweaks to the things in the table e.g. icons
Add a new CLI command: `linkerd profile --template` which outputs a sample service profile yaml. Users can edit this sample and then `kubectl apply` it to add a service profile. The sample serves as "documentation by example" of what service profiles may contain.
Example usage:
```bash
linkerd profile -n emojivoto --template web-svc > web-svc-profile.yaml
# edit web-svc-profile.yaml in your favorite editor
kubectl apply -f web-svc-profile.yaml

Switch the dashboard's component library from antd to material-ui.
There are extensive changes to most of the frontend components in the app.
This branch changes all uses of antd components to their closest equivalent in
material. There is still a lot of polish that needs to go into the look of
individual components, but since the major component rewrites are done, I think
get this work in so that further work can be done in smaller branches.
Changes in this branch:
- add Material-UI 3.2.2 to the project
- replace all uses of antd with material-ui components
- remove antd from the project
- slight modifications of eslint rules
- restructuring of app components to be rendered under the Navigation
component
- deleted most of our css (replaced with material's inline styles)
- pinned package versions in package.json (mostly removing ^)

We implement the getProfiles method in the destination service. This method returns a stream of destination profiles for a given authority. It does this by looking up the ServiceProfile resource in the controller namespace named `<svc>.<ns>` where `<svc>` is the name of the service and `<ns>` is the namespace of the service.
This PR includes:
* Adding a ServiceProfile Custom Resource Definition to linkerd install
* A watch based implementation of the getProfiles method in the destination service, similar to the implementation of get.
* An update to the destination client script that allows querying the getProfiles method.

Use jest for assertions, removing the need for mocha and chai
- Clean up test dependencies
- Move dev dependencies to devDependencies
- yarn remove chai remove sinon-chai mocha
Jest is faster, has more flexibility to run a subset of the tests, and will allow
us to remove a bunch of our assertion libraries.
Many thanks to @grampelberg for prior work on this (#1000)
This PR:
- changes the test runner from karma to jest
- moves individual tests from /test/ to/js/components` where jest expects them

* Support auto sidecar-injection
1. Add proxy-injector deployment spec to cli/install/template.go
2. Inject the Linkerd CA bundle into the MutatingWebhookConfiguration
during the webhook's start-up process.
3. Add a new handler to the CA controller to create a new secret for the
webhook when a new MutatingWebhookConfiguration is created.
4. Declare a config map to store the proxy and proxy-init container
specs used during the auto-inject process.
5. Ignore namespace and pods that are labeled with
linkerd.io/auto-inject: disabled or linkerd.io/auto-inject: completed
6. Add new flag to `linkerd install` to enable/disable proxy
auto-injection
Proposed implementation for #561.
* Resolve missing packages errors
* Move the auto-inject label to the pod level
* PR review items
* Move proxy-injector to its own deployment
* Ignore pods that already have proxy injected
This ensures the webhook doesn't error out due to proxy that are injected using the command
* PR review items on creating/updating the MWC on-start
* Replace API calls to ConfigMap with file reads
* Fixed post-rebase broken tests
* Don't mutate the auto-inject label
Since we started using healhcheck.HasExistingSidecars() to ensure pods with
existing proxies aren't mutated, we don't need to use the auto-inject label as
an indicator.
This resolves a bug which happens with the kubectl run command where the deployment
is also assigned the auto-inject label. The mutation causes the pod auto-inject
label to not match the deployment label, causing kubectl run to fail.
* Tidy up unit tests
* Include proxy resource requests in sidecar config map
* Fixes to broken YAML in CLI install config
The ignore inbound and outbound ports are changed to string type to
avoid broken YAML caused by the string conversion in the uint slice.
Also, parameterized the proxy bind timeout option in template.go.
Renamed the sidecar config map to
'linkerd-proxy-injector-webhook-config'.
