Add changes for edge-21.4.1 (#5980)

## edge-21.4.1

This is a release candidate for `stable-2.10.1`!

This includes several fixes for the core installation as well the Multicluster,
Jaeger, and Viz extensions. There are two significant proxy fixes that address
TLS detection and admin server failures.

Thanks to all our 2.10 users who helped discover these issues!

* Fixed TCP read and write bytes/sec calculations to group by label based off
  inbound or outbound traffic
* Updated dashboard build to use webpack v5
* Modified the proxy-injector to add the opaque ports annotation to pods if
  their namespace has it set
* Added CA certs to the Viz extension's `metrics-api` container so that it can
  validate the certifcate of an external Prometheus
* Fixed an issue where inbound TLS detection from non-meshed workloads could
  break
* Fixed an issue where the admin server's HTTP detection would fail and not
  recover; these are now handled gracefully and without logging warnings
* Aligned the Helm installation heartbeat schedule to match that of the CLI
* Fixed an issue with Multicluster's serivce mirror where it's endpoint repair
  retries were not properly rate limited
* Removed components from the control plane dashboard that now are part of the
  Viz extension
* Fixed components in the Jaeger extension to set the correct Prometheus scrape
  values
