Enable logging.conf & fluentd for aodh

This change introduce ability to use log_config_append parameter with
new FluentdHandler to send logs directly to Fluentd.

To save per binary log streams as it is in the default logging states generates
separate logging.conf files per service and use /etc/default/<service name>
to pass dedicated logging.conf to every service.

New prometheus metrics now available:

  * log_messages - total number of log lines per severity
  * openstack_http_response_times - set of HTTP-stats metrics per HTTP method and status:
    - three quantiles, 50%, 90% and 99% for response time
    - sum of response time
    - count of responses
