Merge from DEV/SITE_CONFIGURABILITY to HEAD

22049: ALF-3786 Partial implementation of Configurable Site Creation Group.
         Site configuration groups can be configured via permissions management in the usual way.
         This check-in adds hasCreateSitePermissions() to various SiteService layers to better support
         client code when site creation restrictions have been imposed.
