Using with_rhev flag in spec to configure rhev changes if required

This flag will allow to set specific restrictions when building vdsm
as part of rhev.

* dumpStorageTable.py was moved[1][2] from vdsm-cli to vdsm package.

  As result when updating vdsm without vdsm-cli there is a conflict
  between the old vdsm-cli and the new vdsm packages.

  Our old bootstrap code which is shipped with rhevm-3.0 installs
  packages one by one, failing any bootstrap if such conflict exists.

  The temporary simplest solution is to pull vdsm-cli into dependency try
  of vdsm package, this dependency will be removed in future when
  newer vdsm-bootstrap be distributed to all rhevm machines.

* Disabling creation of gluster packages during vdsm make process
