This PR adds `--ha` flag for `viz install` which overrides with
the `values-ha.yaml` of the viz chart. This PR adds these functions
in `pkg/charts` so that the same can be re-used elsewhere.
## Testing
```bash
tarun in dev in on k3d-deep () linkerd2 on tarun/viz-ha-nits [$?] via 🐹 v1.15.4 took 2s
❯ ./bin/go-run cli viz install | grep 1024

* viz: add a new uninstall command
This adds a new `linkerd viz uninstall` command emitting the resources
with the `linkerd.io/extension=linkerd-viz` label set.
* 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.
