feat(installer): Add initcontainers to prevent installation errors

[agardnerIT]

This PR

• Adds initContainers to prevent Errors and CrashLoopBackOffs during a Keptninstallation.

Related Issues

Fixes #7580

Notes

This is my "best guess" as to the order of the dependencies and probably needs adjusting.

Follow-up Tasks

This is a temporary fix and should be solved with other methods (like improved readiness probes and health checks).

How to test

Install a version without this PR and you'll see the pods fall into Error and CrashLoopBackOff states until everything settles down. This is due to dependencies between the Keptn pods.

Install this version and initcontainers should prevent Errors and CrashLoopBackOffs.

@agardnerIT did you try a solution with just readiness probes instead of init containers?

No. I'm at the limit of my knowledge here so any assistance or better solutions to move this PR towards being ready for a merge is appreciated.

I will look into it soon, sorry for the long wait, vacation, other prios in Keptn...
