[INSTRM-2161] Publicize actor version issues

Relates — Fri, 2 Feb 2024 15:43:12 +0000

We need to check running actor versions and alert on any possible discrepancies. Specifically:

alert when a running actor's version differs from the current eups version
alert when the version of any running actor's dependencies differs from the version installed with the running actor.

We can additionally note (but not as a warning/alert) when a newer version of a dependency is available. Not sure about this.

The proposal is to have the checks done in the existing version command, as implemented in ics_utils. The result would be propagated in a a new field added to the end of the existing *_version keys.

As far as displaying the issues go, we propose adding a new "channel" to the existing alertsActor for displaying "observing" warnings. Besides these version mismatches, some obvious keys might be ingest/reduce errors, or timing problems (getVisit, convergence ,ramp writes, etc), etc. These would be enumerated by adding a new field to the existing actorkeys dictionaries, just as we do for FITS and STS flags.

Obviously, child tickets to be linked in.
