[JENKINS-63971] prepare for casc support of node monitors

[mawinter69]

to support node monitors in casc, is is essential that they have DataBoundConstructors defined and a proper symbol is used.

Testing done

Tested with jenkinsci/configuration-as-code-plugin#2392 that the monitors are properly exported and can be imported.

export looks like this:

nodeMonitors:
  - diskSpaceMonitor:
      freeSpaceThreshold: "3GB"
  - tmpSpace:
      freeSpaceThreshold: "3GB"
  - jvmVersion:
      comparisonMode: EXACT_MATCH
      disconnect: true
  - inodesMonitor:
      inodesPercentThreshold: "98%"
  - remotingVersion:
      ignored: true

This looks great to me. Thanks very much. I need to test it before I merge it. That may take a few days because I am currently traveling and won't return until the end of the week.

Thanks as well. Adding JCasC support for for nodeMonitor is a must.

I was testing similar changes when implementing #192 and I confirm changes in the descriptor behave as expected

[MarkEWaite]

I've confirmed that with the configuration as code pull request and this pull request, I see the configuration as code entries. The configuration as code pull request is required before the results of this pull request will be visible to users.

[MarkEWaite]

I've marked this pull request as a draft because the required pull configuration as code pull request is a draft.
