SCIM support for the control plane

[Kamillaova]

SCIM is a standardized way to synchronize users between an application and an IdP (or an IdP with an IdP), AFAIU Netbird currently has no way to synchronize (in real time) Netbird's ACL groups from an IdP, adding SCIM support would solve that problem.

Such a task could also be implemented by using IdP-specific API endpoints or so, but that's not good since it's an IdP-specific solution.
For example, #2073. If retrieving user information was implemented in a standardized way, this problem wouldn't exist. (I also really can't understand why it's implemented in an IdP-specific way, lol)

I also seen this comment from 2023: zitadel/zitadel#1931 (comment)

correct me if I'm wrong, but isn't SCIM sync a feature of hosted netbird?

Feature of hosted netbird - syncing from azure ad, okta, google ws, but not with generic SCIM
