    Tune tweak::apache_wrappers module

    - Sometimes apache fails to start after stop, due to unclosed
      resources. The problem frequently reproduced with keystone wsgi
      module, and didn't reproduced with horizon or radosgw.
      'apachectl restart' is recommended if doing start/stop rapidly

    - Redefine restart => 'apachectl graceful' for apache service
    - Remove disabling of GarbageCollector
