Title:
  local configuration is not allowed in "keystone-paste.ini"

Status in OpenStack Identity (keystone):
  Fix Released

Bug description:
  According to funcation docs in keystone/common/wsgi.py, local
  configuration is allowed in the paste.deploy config files, such as
  "redis_host".

  https://github.com/openstack/keystone/blob/73ad4036d62b3aa7cf50e11ddf7bee8278bbe4d0/keystone/common/wsgi.py#L380-L402

  And in the following implementation, local configuration is indeed
  read from paste.deploy config files.

  https://github.com/openstack/keystone/blob/73ad4036d62b3aa7cf50e11ddf7bee8278bbe4d0/keystone/common/wsgi.py#L406

  But, the local_config is not allowed in the constructor where only
  "app" is passed into the constructor.

  https://github.com/openstack/keystone/blob/73ad4036d62b3aa7cf50e11ddf7bee8278bbe4d0/keystone/common/wsgi.py#L409-L411

  
  So, if we configure paste.deploy config files like what the method docs says, it will always fails as:
