* viz: move some components into linkerd-viz
This branch moves the grafana,prometheus,web, tap components
into a new viz chart, following the same extension model that
multi-cluster and jaeger follow.
The components in viz are not injected during install time, and
will go through the injector. The `viz install` does not have any
cli flags to customize the install directly but instead follow the Helm
way of customization by using flags such as
`set`, `set-string`, `values`, `set-files`.
**Changes Include**
- Move `grafana`, `prometheus`, `web`, `tap` templates into viz extension.
- Remove all add-on related charts, logic and tests w.r.t CLI & Helm.
- Clean up `linkerd2/values.go` & `linkerd2/values.yaml` to not contain
fields related to viz components.
- Update `linkerd check` Healthchecks to not check for viz components.
- Create a new top level `viz` directory with CLI logic and Helm charts.
- Clean fields in the `viz/Values.yaml` to be in the `<component>.<property>`
model. Ex: `prometheus.resources`, `dashboard.image.tag`, etc so that it is
consistent everywhere.
**Testing**
```bash
# Install the Core Linkerd Installation
./bin/linkerd install | k apply -f -
# Wait for the proxy-injector to be ready
# Install the Viz Extension
./bin/linkerd cli viz install | k apply -f -
# Customized Install
./bin/linkerd cli viz install --set prometheus.enabled=false | k apply -f -
```
What is not included in this PR:
- Move of Controller from core install into the viz extension.
- Simplification and refactoring of the core chart i.e removing `.global`, etc.

The rare cases where these tests were useful don't make up for the burden of
maintaing them, having different k8s version change the messages and
having unexpected warnings come up that didn't affect the final
convergence of the system.
With this we also revert the indirection added back in #4538 that
fetched unmatched warnings after a test had failed.
Most invocations of `TestHelper.LinkerdRun` don't actually need the stderr
output except to encode it in the error message. This changes this helper
to return an error that includes the full invoked command and error message.
Invocations that need direct access to stderr must call `TestHelper.PipeToLinkerdRun`
This PR adds a new cli test to see if installation yamls are correctly
generated even on windows, this is important because of all the file
path difference between windows and Linux, and if any code uses a wrong
format might cause the chart generation commands to fail on windows.
This creates a separate workflow for both release and integration.
Also, all the exisiting integration tests are moved in to
/tests/integration to separate from /test/cli as this test does not fall
under integration tests category
