This edge release adds more flexibility to the MeshTLSAuthentication and
AuthorizationPolicy policy resources by allowing them to target entire
namespaces. It also fixes a race condition when multiple CNI plugins are
installed together as well as a number of other bug fixes.

* Added support for MeshTLSAuthentication resources to target an entire
  namespace, authenticating all ServiceAccounts in that namespace
* Fixed a panic in `linkerd install` when the `--ignore-cluster` flag is passed
* Fixed issue where pods would fail to start when `enablePSP` and
  `proxyInit.runAsRoot` are set
* Added support for AuthorizationPolicy resources to target namespaces, applying
  to all Servers in that namespace
* Fixed a race condition where the Linkerd CNI configuration could be
  overwritten when multiple CNI plugins are installed
* Added test for opaque ports using Service and Pod IPs (thanks @krzysztofdrys!)
* Fixed an error in the linkerd-viz Helm chart in HA mode
