Enable keystone logging on debian

This commit enables keystone logging to /var/log/keystone/keystone.log
and makes the default log level as INFO.

Test plan:

PASS: Full build, install, bootstrap and unlock
PASS: Run authenticated commands such as 'system host-list' and verify
      that it gets logged to /var/log/keystone/keystone.log
