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
This patch makes hostname an optional field. Currently here are metrics
that have no hostname:
- Some metrics provided by hypervisor_stats:
- total_free_disk_GB
- total_free_ram_MB
- total_free_vcpus
- total_used_disk_GB
- total_used_ram_MB
- total_used_vcpus
- total_running_instances
- total_running_tasks
- all metrics collected by check_openstack_api
- all metrics collected by http_check

The logs_counter filter needs to discard the log messages that are not in the
current interval otherwise the aggregated metrics can be incorrect.

This change adds a new filter that processes OpenStack logs and adds a new
field that contains the number of logs per service and level to produce a
new metric. The metric is the number of logs written per second.
