KeyError: 'user_id' in devstack logs

[Kaitlin Farr]

When running devstack with Barbican enabled, the Barbican logs have multiple entries of the following error:

Traceback (most recent call last):
  File "/usr/lib/python2.7/logging/__init__.py", line 851, in emit
    msg = self.format(record)
  File "/usr/local/lib/python2.7/dist-packages/oslo_log/handlers.py", line 115, in format
    return logging.StreamHandler.format(self, record)

    s = self._fmt % record.__dict__
KeyError: 'user_id'
Logged from file context.py, line 41

Related to bug 1431784

Proposed fix: update lib/barbican from:
     setup_colorized_logging $BARBICAN_CONF DEFAULT "project_id" "user_id"
to:
    setup_colorized_logging $BARBICAN_CONF DEFAULT project user

    Fix colorized logging in Devstack

    When running Barbican with Devstack, the logs would have multiple
    entries of "KeyError: 'user_id'". This resolves that error.
