edge-21.6.1

This release adds support for retrying HTTP/2 requests with small (<64KB)
message bodies, allowing the proxy to properly buffer message bodies when
responses are classified as a failure. Documentation on how to configure
retries can be found here.

This release also modifies the proxy's identity subsystem to instantiate a
client on-demand so client connections are not retained continually. Also
included in this release are various bug fixes and improvements as well as
expanding support for resource-aware tab completion in the jaeger and
multicluster CLI extensions.

• Added support for specifying a gateway-port flag for the multicluster link
  command (thanks @psmit!)
• Added support for Kubernetes resource aware tab completion for jaeger and
  multicluster commands
• Fixed an issue where viz, jaeger and multicluster extensions could not
  be installed on PodSecurityPolicy-enabled clusters
• Fixed an issue where linkerd check --proxy could incorrectly report
  out-of-date proxy versions caused by incorrect regex (thanks @aryan9600!)
• Added support for the proxy to retry HTTP/2 requests with message bodies
  <= 64KB
• Modified the proxy's controller stack to create new client connections
  on-demand
• Fixed Viz's uninstall command to remove viz installations that used the
  legacy linkerd.io/extension: linkerd-viz label (thanks @jsoref!)
• Expanded the "linkerd-existence" health check to also check for the
  destination pod readiness
