[QA] Please add test to check start/stop/restart lma_collector (heka) and collectd services

Due to we have the same behavior on customer's environments, where we restarting lma_collector (hekad) and collectd services via "kill -9 " please add test to check start/stop/restart lma_collector (heka) and collectd services.

Test plan should contain next steps:

1 create environment with LMA plugins installed.
2 create close to production load! Environment should generate a lot of logs during test. The load should be periodical.
3 move vip__management service into pacemaker to another controller node
4 ensure that lma_collector (heka) sending data to eleasticsearch, influxdb, nagios
5 in 1 hour move vip__management service into pacemaker to another controller node
6 ensure that lma_collector (heka) sending data to eleasticsearch, influxdb, nagios
7 check PID of hekad and collectd on all nodes ans save this data
8 stop lma_collector (heka) via "pcs resource disable lma_collector"
9 wait while pcs report that lma_collector (heka) stopped on all controllers
10 check PID of hekad and (collectd - need deeper investigation if it stopped too or we do not need to stop it) on all controllers. If hekad PID exist - test failed
11 stop lma_collector (heka) via "pcs resource enable lma_collector"
12 wait while pcs report that lma_collector (heka) started on all controllers.
13 check that data was correctly sent to eleasticsearch, influxdb, nagios
14 from fuel master nodes restart lma_collector on all nodes except controllers via
"for i in fuel nodes............; do ......... initctl restart lma_collector; done"
15 check lma_collector (heka) PID and compare it with PID from step 7. If you see even 1 the same PID - test failed.
16 check that data was correctly sent to eleasticsearch, influxdb, nagios
17 from fuel master nodes stop lma_collector on all nodes except controllers via
"for i in fuel nodes............; do ......... initctl stop lma_collector; done"
18 check lma_collector (heka) PID, if exist - test failed
19 from fuel master nodes start lma_collector on all nodes except controllers via
"for i in fuel nodes............; do ......... initctl start lma_collector; done"
20 check that data was correctly sent to eleasticsearch, influxdb, nagios

steps 14-20 should be applied to collectd service too
#/etc/init.d/collectd
Usage: /etc/init.d/collectd {start|stop|restart|force-reload|status}
