Report the overall health of SDP to TM

Interface to report the overall health of SDP to TM (e.g. as an attribute on the master TANGO device). Should make a good attempt at being able to catch all top-level SDP errors, e.g. check that all service deployments are up in Kubernetes.

<TODO>

• eg. feedback the state of deployments of the workflow 
• Helm deployer monitors deployments (IP, failure, ...) and we publish status via Tango.
  • (link to workflow library continuation)
• Determine: Master device vs subarray device vs other device?
• Use case: propagate deployment failure
