CBQE-0: add group "ALL" that run tests with any GROUPS

i'm going to add these parameter to run jenkins jobs
for example, test suite have groups:P0,P1,P2,GRACEFUL
-p GROUP=ALL - run all tests
-p GROUP=ALL,EXCLUDE_GROUP=GRACEFUL - all tests without GRACEFUL group

I also planning to include "ALL" group in jenkins template http://qa.hq.northscale.net/view/All/job/LINUX_JOB_TEMPLATE/
