Make the auto_link_user OmniAuth setting configurable by provider
Release notes
Make the auto_link_user OmniAuth setting configurable by provider.
Problem to solve
The auto_link_user OmniAuth setting was introduced in !36664 (merged)
The current implementation is a true/false setting that applies to all providers.
In the MR, it was suggested to make the setting configurable for provider:
gitlab_rails['omniauth_auto_link_user'] = ['saml', 'google_oauth2']Intended users

User experience goal
Site admins can set which OmniAuth strategies have the auto_link_user setting for.
Proposal
Support checking that the current OmniAuth provider is in the supported array before auto linking the user via email.
