Make OIDC configurable in GUI

[DickPostma]

Is your feature request related to a problem? Please describe.
OIDC Configuration is setup on an system environment level. This is now an OPS or an system administrator tasks.
Datamanagers or Application managers should have the option to change or add OIDC details.
After installation Admins need OPS to change details. In the most cohorts this is an long and slow process.

Describe the solution you'd like
An configurable option in the admin settings with:

MOLGENIS_OIDC_CLIENT_ID // the id for the molgenis instance as set in the authentication provider
MOLGENIS_OIDC_CLIENT_SECRET // the client secret as set in the authentication provider (Password field so not visible to external users)
MOLGENIS_OIDC_CLIENT_NAME // the client name as set in the authentication provider, defaults to MolgenisAuth
MOLGENIS_OIDC_DISCOVERY_URI // location of authentication provider (with path to relevant service)
MOLGENIS_OIDC_CALLBACK_URL // public available endpoint for molgenis service to handle the login action ( https://[public server location]/_callback, note the '_callback' is added by the molgenis server )
