Introduce Monitor support for CSR resource

These changes allow the Monitor to also track CSR
(CertificateSigningResource) resources which will make
it possible to know when a certificate has been issued by
the K8s cluster signer. In turn, DCM will be able to read,
store and use that certificate to generate kubeconfigs.

Out-of-tree actions required:
- publish monitor's docker image built from this source
  onto emcov2/monitor:latest
