Add changes for edge-21.1.2 (#5538) 

## edge-21.1.2

This edge release continues the work on decoupling non-core Linkerd components.
Commands that use the viz-extension i.e, `dashboard`, `edges`, `routes`,
`stat`, `tap` and `top` are moved to the `viz` sub-command. These commands are still
available under root but are marked deprecated and will be removed in a
later stable release.

This release also features proxy's dependencies upgrade to the
Tokio v1 ecosystem.

* Moved sub-commands that use the viz-extension under `viz`
* Started ignoring pods with status.phase=Succeeded when watching IP addresses
  in destination. This is useful for re-use of IPs of terminated pods
* Support Bring your own Jaeger use-case by adding `collector.jaegerAddr` in
  the jaeger extension.
* Fixed an issue with the generation of working manifests in the
  `podAntiAffinity` use-case
* Added support for the modification of proxy resources in the viz
  extension through `values.yaml` in Helm and flags in CLI.
* Improved error reporting for port-forward logic with namespace
  and pod data, used across dashboard, checks, etc
  (thanks @piyushsingariya)
* Added support to disable the rendering of `linkerd-viz` namespace
  resource in the viz extension (thanks @nlamirault)
* Made service-profile generation work offline with `--ignore-cluster`
  flag (thanks @piyushsingariya)
* Proxy's Tap API is disabled by default and it is enabled only when
  `LINKERD2_PROXY_TAP_SVC_NAME` configuration is set. This means that
  `LINKERD2_PROXY_TAP_DISABLED` is no longer honored
* Upgraded the proxy's dependencies to Tokio v1 ecosystem
