* extension: Add new jaeger binary
This branch adds a new jaeger binary project in the jaeger directory.
This follows the same logic as that of `linkerd install`. But as
`linkerd install` VFS logic expects charts to be present in `/charts`
directory, This command gets its own static pkg to generate its own
VFS for its chart.
This covers only the install part of the command

Fixes#4874
This branch upgrades Helm sdk from v2 to v3 *without any functionaly
changes*, just replacing types with newer API's.
This should not effect our current support for Helm v2 as we did not
change any of the underlying tempaltes(which work with Helm v2). This
works becuase we did not use any of the API's that read the Chart
metadata (which are the only ones changed from v2 to v3) and currently
manually load files and pass ito the sdk.
This PR should provide a great point to start more of the newer Helm v3
API's including for the upgrade workflow thus allowing us to make
Linkerd CLI more simpler.

This PR removes the service mirror controller from `linkerd mc install` to `linkerd mc link`, as described in https://github.com/linkerd/rfc/pull/31. For fuller context, please see that RFC.
Basic multicluster functionality works here including:
* `linkerd mc install` installs the Link CRD but not any service mirror controllers
* `linkerd mc link` creates a Link resource and installs a service mirror controller which uses that Link
* The service mirror controller creates and manages mirror services, a gateway mirror, and their endpoints.
* The `linkerd mc gateways` command lists all linked target clusters, their liveliness, and probe latences.
* The `linkerd check` multicluster checks have been updated for the new architecture. Several checks have been rendered obsolete by the new architecture and have been removed.
The following are known issues requiring further work:
* the service mirror controller uses the existing `mirror.linkerd.io/gateway-name` and `mirror.linkerd.io/gateway-ns` annotations to select which services to mirror. it does not yet support configuring a label selector.
* an unlink command is needed for removing multicluster links: see https://github.com/linkerd/linkerd2/issues/4707
* an mc uninstall command is needed for uninstalling the multicluster addon: see https://github.com/linkerd/linkerd2/issues/4708

This change adds a `allow` and `link` commands, effectivelly enabling a cluster to have more than one set of credentials that allow it to be mirrored.

This PR introduces a few changes that were requested after a bit of service mirror reviewing.
- we restrict the RBACs so the service mirror controller cannot read secrets in all namespaces but only in the one that it is installed in
- we unify the namespace namings so all multicluster resources are installedi n `linkerd-multicluster` on both clusters
- fixed checks to account for changes
