This release updates Linkerd to store the identity trust root in a ConfigMap to make it easier to manage and rotate the trust root. The release also lays the groundwork for StatefulSet support in the multicluster extension and removes deprecated PSP resources by default. * Added a `linkerd-identity-trust-roots` ConfigMap which contains the configured trust root bundle * Introduced support for StatefulSets across multicluster (disabled by default) * Stopped installing PSP resources by default since these are deprecated as of Kubernetes v1.21
