feat: added impl for kube prometheus monitor

Updates  to use  for managing
Discord webhook adapter deployments. This prevents redundant installations
by ensuring that the deployment interpret for a given adapter
configuration is executed only once.

The internal state now uses a  keyed by the alertreceiver ID to
track and initialize each receiver's .
