vdsm_pep8_gerrit final fix

[Nir Soffer]

Hi infra,

http://jenkins.ovirt.org/job/vdsm_pep8_gerrit/ is finally fixed.

If modified the --filename pattern today from:

    "*.py,*.py.in,*vdsm*"

To:

    "*.py,*.py.in,*/vdsm,*/supervdsmServer"

So we match both ./vdsm/vdsm and ./vdsm/supervdsmServer, but will not match files such as
./doc/vdsm.txt. We don't have yet such file but it will be annoying if pep8 breaks our 
build because we added file that matches *vdsm*.

Now the only think left is get this script into git.

Thanks,
Nir
