`GET /groups?order_by=similarity` is supported but not available in the
high level API
https://gitlab.com/gitlab-org/gitlab/-/issues/332889

Settings having only a single Type caused a NullPointer when
printing the allowed types.

Improves #818

Fixed de-serialization of MembershipSourceType by letting the JacksonJsonEnumHelper know that the first letter should be capitalized

Actually fetch all the memberships with UserAPI.getMemberships() and also provide a pager based method for lazy fetching

Use case: oauth2 access limited time tokens which should be updated on regular basis. Supplier allows us to move refresh logic outside client.
Use specified setter to set up supplier after gitlab api object creation.

This makes it possible to stream data coming
from another server straight into the POST request to Gitlab,
saving an extra, expensive, and useless IO operation on disk.

Fix #769
