Currently Quay has the  memberOf attribute hard coded for detecting group memberships for the purpose of LDAP <-> Team sync in a Quay organization.

Some customers are another attribute in their LDAP (not memberOf, but groupMembership) for users to groups assignment. Therefore the Team Sync does not work for them. 

We should implement the ability to customize the membership attribute and use memberOf as a default in the absence of customization.
