Indexer Can Be Installed as a Helm Sub-Chart for Metacat in Kubernetes

[artntek]

In order to support being deployed as a helm sub chart for metacat k8s deployment (see Metacat issue 1665), indexer needs:

• cleanup of hardcoded parameters in yaml templates and values files
• code changes to support healthchecks -- liveness & readiness probes
• and a placeholder for anything else that is discovered during this process...

That sounds great. Do you have a list of those hardcoded params? I didn't think there were many (any), as we've been able to deploy both locally on RD and on several namespaces of the dev cluster. Let's generate a list of what needs to be de-hardcoded, and it should be straightforward to fix those.

As I work through getting everything up and running, I'm collecting the values I've had to override in a separate yaml file. Most of the overrides are because of the namespace being hardcoded (d1index), and while some of those will always need to be overridden manually, there is scope to auto-configure some of them.

There are also the credentials for rmq and solr that need to be moved to secrets
