feat(common): add support for automatic configmaps from file/path

[PrivatePuffin]

Is your feature request related to a problem?

currently configmaps from files can be done, but its not the easiest process.

Describe the solution you'd like

We should do something like bjws-s common does:
https://github.com/bjw-s/helm-charts/blob/8f66d48e6e21704bd62ffa12e70333aa3e3cf117/charts/library/common/values.yaml#L486

Describe alternatives you've considered

Keeping it as is, but no progress is not a realistic option

Additional context

.

I've read and agree with the following

• I've checked all open and closed issues and my request is not there.

Interesting feature. I did in a Kustomization:

configMapGenerator:
  - name: authelia-configfile
    files:
      - ./config/configuration.yaml
generatorOptions:
  disableNameSuffixHash: true

I assume that will give the same result as above.

However for clustertool users, the folder with this configuration file, get with a clustertool genconfig an extra kustomization.yaml generated in that config folder.

Maybe something to keep in mind?

Thats not related to this issue.
The goal of this issue is just feature parity.

The goal is not that it's currently not possible. It's already possible in multiple ways and we also already do this btw.
Also: You're wrong, because the issue is about AUTOMATIC configmaps for MULTIPLE files.
