This is a release candidate for stable-2.14.0; we encourage you to help trying it out! This edge release contains a number of improvements over the multi-cluster features introduced in the last edge release supporting flat networks. It also hardens the containers security stance by removing write access to the root filesystem. * Enhanced `linkerd multicluster link` to allow clusters to be linked without a gateway ([#11226]) * Added cluster store size gauge metric ([#11256]) * Disabled local traffic policy for remote discovery ([#11257]) * Fixed various innocuous multi-cluster warnings ([#11251], [#11246], [#11253]) * Set `readOnlyRootFilesystem: true` in all the containers, as they don't require write permissions ([#11221]; fixes [#11142]) (thanks @mikutas!)

We add a
cluster_store_sizegauge to the destination controller to track the number of entries in the remote discovery cluster store. If this is ever different from the number of cluster credentials secrets in the linkerd namespace, this indicates that there is a problem with a link that needs to be investigated further.
