Using bulk metrics for the log counters reduces largely the likelihood
of blocking the Heka pipeline. Instead of injecting (x services
* y levels) metric messages, the filter injects only one big message.
This changes also updates the configuration of the metric_collector
service to deserialize the bulk metric to support alarms on log
counters.

Closes-Bug: #1643280
HTTP metrics are now statistics aggregated every 10 seconds.
A new metric is emitted openstack_<service>_response_times with these
values:
- min
- max
- sum
- count
- percentile
Hence, the previous metric disappears (openstack_<service>_responses).
