Ivan Kolodyazhny bce886ea7e Add support for processutils.execute
oslo.privsep should be used by default. We should be able to use
processutils.execute when os-brick is used outside Nova or Cinder.

E.g.: python-brick-cinderclient-ext should be used with sudo or run
as root without any helpers like oslo.privsep or oslo.rootwrap.

"""Generic exec utility that allows us to set the

Some projects need their own execute wrapper
