Provide fixes to tungten/patrole plugins

This is needed to run contrail tests
Tungsten part of fixes:
1. Added get_auth_providers method to use in tests
2. Modified resource_setup method to do not fail
if project already exists. In our case it has created
by tempest plugin
3. Remove check for CONF.patrole.enable_rbac due to deprecation of 
this parameter in next version of patrole plugin.

Added .gitreview
