Issue with ConfigInitializer not supporting the new OAuth

[Frooodle]

ConfigInitializer script is done badly and doesnt support 3 layered configs like the OAuth section. And has issues with tags of same name (two enabled etc)

Script should be fixed to allow better merging of yml files etc

The enable in oauth is actually not necessary, if oauth is activated, then the function is activated. Or have I thought incorrectly about that?

[Frooodle]

it could be done via a config presence check instead of a enable flag itself but due to how spring beans work it needs some conditional check

[Ludy87]

There should be clarity by checking the issuer, clientId and clientSecret

[Frooodle]

Fixed by splitting settings.yml and custom_settings.yml Settings.yml is stirling-pdf settings custom_settings.yml is any user entered settings such as server.port etc

[Frooodle]

Im a idiiot keeping this open

I think it can be closed -> #1284
