Problem Description

Group management varies between OAuth, LDAP, and trusted header authentication methods leading to lack of features depending on which auth model the deployment is using.

Desired Solution you'd like

1. Create a single util class that will create a standard approach for group management during log in attempts
2. Create a generic set of config values for use in the new group util:
   1. ENABLE_GROUP_MANAGEMENT
      If false then group management is not performed
   2. ENABLE_GROUP_CREATION
      If false then unrecognized groups will not be created.
   3. BLOCKED_GROUPS
      A list of groups that will not be sync'ed with the application
3. Continue support for the following config values until they are deprecated
   1. ENABLE_OAUTH_GROUP_MANAGEMENT
   2. ENABLE_OAUTH_GROUP_CREATION
   3. OAUTH_BLOCKED_GROUPS
   4. ENABLE_LDAP_GROUP_MANAGEMENT
   5. ENABLE_LDAP_GROUP_CREATION

@tjbck You closed my PR that achieved this feat without any reasoning why. Could you elaborate here?
