cmd/k8s-operator: add multi replica support for recorders (#17864)

Browse Source 
This commit adds the `spec.replicas` field to the `Recorder` custom
resource that allows for a highly available deployment of `tsrecorder`
within a kubernetes cluster.

Many changes were required here as the code hard-coded the assumption
of a single replica. This has required a few loops, similar to what we
do for the `Connector` resource to create auth and state secrets. It
was also required to add a check to remove dangling state and auth
secrets should the recorder be scaled down.
