This can happen when one other node in the cluster such as a client is unable to communicate with the leader server and sees it as failed. When that happens its failing status eventually gets propagated to the other servers in the cluster and eventually this can result in RPCs returning “No cluster leader” error.
That error is misleading and unhelpful for determing the root cause of the issue as its not raft stability but rather and client -> server networking issue. Therefore this commit will add a new error that will be returned in that case to differentiate between the two cases.
Previously the tokens would fail to insert into the secondary's state
store because the AuthMethod field of the ACLToken did not point to a
known auth method from the primary.
Backport of #9351 to 1.8.x
A vulnerability was identified in Consul and Consul Enterprise (“Consul”) such that operators with `operator:read` ACL permissions are able to read the Consul Connect CA configuration when explicitly configured with the `/v1/connect/ca/configuration` endpoint, including the private key. This allows the user to effectively privilege escalate by enabling the ability to mint certificates for any Consul Connect services. This would potentially allow them to masquerade (receive/send traffic) as any service in the mesh.

This PR increases the permissions required to read the Connect CA's private key when it was configured via the `/connect/ca/configuration` endpoint. They are now `operator:write`.

The Catalog, Config Entry, KV and Session resources potentially re-validate the input as its coming in. We need to prevent snapshot restoration failures due to missing namespaces or namespaces that are being deleted in enterprise.
