Add jenkins test group to TestRail report

[Andrey Sledzinskiy]

Need to add 'test group' info that was used by jenkins to TestRail.
It will ease the process of finding tests in report

[Nastya Urlapova (aurlapova)]

@Andrey, did you mean - test thread in jenkins?

[Andrey Sledzinskiy (asledzinskiy)]

Yeah, I meant test thread in jenkins

[Artem Panchenko (apanchenko-8)]

@Andrey,

results in tests run already have such info, you can find it in 'version' field (or inside job build URL). For example: the latest result of the 'deploy_stop_reset_on_ha' tests on CentOS and ISO #101 has version '2015-02-07_04-09-57_cluster_actions_on_6.1-101', that means it was ran on 2015-02-07 at 04:09:57 UTC, inside 'cluster_actions' test group on Fuel 6.1 (iso # 101).
