stackablectl demo install should optionally ignore existing Jobs

[NickLarsenNZ]

Affected version

24.7.1

Current and expected behavior

I should be able to rerun a demo install to create any missing objects (eg: if I deleted something like a SparkApplication and want to reapply it).

Currently stackablectl fails because the Jobs are immutable (in my case because I want to upgrade from 24.7 to dev), but I don't want the setup jobs to run again.

Possible solution

I have a few ideas in mind to cater to various behaviours:

1. Continue applying the remaining resources and display which failed to apply at the end. Let the user then decide if certain Jobs should be rerun by them manually deleting the applicable jobs.
2. Add labels to certain jobs that are idempotent (safe to be recreated and run again), and jobs that should be ignored (initial setup jobs, eg: for Keycloak).
