edge-20.12.1 (#5324)

This edge release continues the work of decoupling non-core Linkerd components
by moving more tracing related functionality into the Linkerd-jaeger extension.

* Continued work on moving tracing functionality from the main control plane
  into the `linkerd-jaeger` extension
* Fixed a potential panic in the proxy when looking up a socket's peer address
  while under high load
* Added automatic readme generation for charts (thanks @GMarkfjard!)
* Fixed zsh completion for the CLI (thanks @jiraguha!)
* Added support for multicluster gateways of types other than LoadBalancer
  (thanks @DaspawnW!)
