Redefine alerting property

The alerting property can be one of 'disabled', 'enabled' or
'enabled_with_notification'

Add timezone support for system logs

Currently Syslog doesn't log the priority ('<PRI>').

Rename netlink.py to linux_netlink.py

This is to comply to a comment from @cznewt in
https://github.com/tcpcloud/salt-formula-heka/pull/24.

Remove Heka decoder tz handling

Use netlink collectd plugin instead of interface

This patch replaces the "interface" collectd plugin by the "netlink" one. The
"netlink" plugin provides the same metrics as "interface" but plus other
metrics such as the number of dropped packets.

Use same collectd df options as StackLight MOS

Orchestration metadata

This is now handled by the Heka formula the same way for all the Heka sandbox
decoders. https://github.com/tcpcloud/salt-formula-heka/pull/20

if storage.swap is defined

See merge request !15

Remove the log counter filter from meta/heka

This filter should be configured by the heka formula itself.

Sample alarms

xmit_hash_policy to hashing-alghoritm

There is an error in salt doc. Hashing-alghoritm is correct, 90bbf8dc4f/salt/modules/debian_ip.py (L1045)

Add timezone to syslog decoder config

add additional bond interface params

Set "hostname" in the linux_hdd_errors|counters filters

Use the proper module directory

The stacklight module dir is /usr/share/lma_collector/common, not
/usr/share/lma_collector_modules. This fixes it.

Fix decoder name

Remove the alarm-related filters

This fixes the decoder name in meta/heka.yml.

This commit removes the alarm-related filter configuration from meta/heka.yml.
Alarms will be defined in a different way (still under discussion).
