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

See merge request !15

Remove the log counter filter from meta/heka

This filter should be configured by the heka formula itself.
