edge-21.1.4

This edge release continues to polish the Linkerd extension model and improves
the robustness of the opaque transport.

• Improved the consistency of behavior of the check commands between
  Linkerd extensions
• Fixed an issue where Linkerd extension commands could be run before the
  extension was fully installed
• Renamed some extension Helm charts for consistency:
  • jaeger -> linkerd-jaeger
  • linkerd2-multicluster -> linkerd-multicluster
  • linkerd2-multicluster-link -> linkerd-multicluster-link
• Fixed an issue that could cause the inbound proxy to fail meshed HTTP/1
  requests from older proxies (from the stable-2.8.x vintage)
• Changed opaque-port transport to be advertised via ALPN so that new proxies
  will not initiate opaque-transport connections to proxies from prior edge
  releases
• Added inbound proxy transport metrics with tls="passhtru" when forwarding
  non-mesh TLS connections
• Thanks to @hs0210 for adding new unit tests!
