Allow org admins to prevent/block social login for SAML SSO accounts

Problem Definition

When SAML SSO is enabled the users can still use the Continue with ... from https://id.atlassian.com to log in. This might allow them to use a different authentication method (OAuth) than what the Org admins want (SAML SSO).

For example:

1. User has a valid Google account with domain @domain.com
2. The org admins' configured SAML SSO at Atlassian with Okta
3. User will still be able to authenticate with the Continue with Google even if SAML is enforced to their account.

Suggested Solutions

Make it possible for the admins to allow/disallow the social login for their managed accounts.
