Updated the action component to support logger facility

[tuxfight3r]

Provides optional logger facility to action component. default action doesnt expect facility to be declaerd. rspec tests has been updated for the action component to support the new features.

rsyslog::server::actions:
  all_logs:
    type: omfile
    facility: "*.*;auth,authpriv.none"
    config:
      dynaFile: "remoteSyslog"
      specifics: "/var/log/test"
  kern_logs:
    type: omfile
    facility: "kern.*"
    config:
      dynaFile: "remoteSyslog"
      file: "/var/log/kern.log"
      cmd: "/proc/cmdline"
  elasticsearch:
    type: omelasticsearch
    config:
      template: "plain-syslog"
      searchIndex: "logstash-index"
      queue.type: "linkedlist"
      queue.spoolDirectory: "/var/log/rsyslog/queue"
      queue.filename: "dbq"
      queue.maxdiskspace: "100g"
      queue.maxfilesize: "100m"
      queue.SaveOnShutdown: "on"
      server: "10.8.200.38"
      action.resumeretrycount: "-1"
      bulkmode: "on"
      dynSearchIndex: "on"

would create the following content. If the options are less than 3 the content would be on a single line and if it exceeds more than 2 options the content would be formated similar to kern_logs to provide readability.

# all_logs
*.*;auth,authpriv.none         action(type="omfile" dynaFile="remoteSyslog" specifics="/var/log/test" )

# kern_logs
kern.*                         action(type="omfile"  
                                 dynaFile="remoteSyslog"
                                 file="/var/log/kern.log"
                                 cmd="/proc/cmdline"
                               )

# elasticsearch
action(type="omelasticsearch"
  template="plain-syslog"
  searchIndex="logstash-index"
  queue.type="linkedlist"
  queue.spoolDirectory="/var/log/rsyslog/queue"
  queue.filename="dbq"
  queue.maxdiskspace="100g"
  queue.maxfilesize="100m"
  queue.SaveOnShutdown="on"
  server="10.8.200.38"
  action.resumeretrycount="-1"
  bulkmode="on"
  dynSearchIndex="on"
)
