Swann Croiset ebac150f8a Separate the (L)og of the LMA collector
This change separates the processing of the logs/notifications and
metric/alerting into 2 dedicated hekad processes, these services are
named 'log_collector' and 'metric_collector'.

Both services are managed by Pacemaker on controller nodes and by Upstart on
other nodes.

All metrics computed by log_collector (HTTP response times and creation time
for instances and volumes) are sent directly to the metric_collector via TCP.
Elasticsearch output (log_collector) uses full_action='block' and the
TCP output uses full_action='drop'.

All outputs of metric_collector (InfluxDB, HTTP and TCP) use
full_action='drop'.

The buffer size configurations are:
* metric_collector:
  - influxdb-output buffer size is increased to 1Gb.
  - aggregator-output (tcp) buffer size is decreased to 256Mb (vs 1Gb).
  - nagios outputs (x3) buffer size are decreased to 1Mb.
* log_collector:
  - elasticsearch-output buffer size is decreased to 256Mb (vs 1Gb).
  - tcp-output buffer size is set to 256Mb.

#
# == Class lma_collector::logs::swift
#
# Class that configures Heka for reading Swift logs.
#
# The following rsyslog pattern is assumed:
#
# <%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg%\n
#
# Swift only uses syslog and doesn't add its logs to log files located in a
# /var/log/swift/ directory as other OpenStack services do. So we make Swift a
# special case and assume rsyslog is used.
#
# === Parameters:
#
# [*file_match*]
# (mandatory) The log file name pattern. Example: 'swift\.log$'. Example
# for a sequential rotating logfile: 'swift\.log\.?(?P<Seq>\d*)$'. See
# http://hekad.readthedocs.org/en/latest/pluginconfig/logstreamer.html
# for more information.
#
# [*priority*]
# (optional) When using sequential logstreams, the priority defines how
# to sort the logfiles in order from the slowest to newest. Example:
# '["^Seq"]'. See
# http://hekad.readthedocs.org/en/latest/pluginconfig/logstreamer.html
# for more information.
#
# [*log_directory*]
# (optional) The log directory. Default is /var/log.
