[JENKINS][ANN] new ovirt-engine dao unitests gerrit job

[Eyal Edri]

fyi,

i've added a new job [1] to run on each patch for ovirt-engine.
the job runs dao-unit tests for ovirt-engine and it's run time is ~ 3 min.

important reqs:

1. job requires postgres & a db installed.
2. job runs only run changes to:
    packaging/dbscripts/**
    backend/manager/modules/dal/**
3. runs on both master and ovirt-engine-3.3 branches
4. only runs 3 instances ins parallel for now
5. runs only on a specifc slave for now - requires adding puppet class for other 
   slaves to ensure postgres.


If you encounter any issues/problems, replay on the thread please.

Eyal.
