Add Fuel Nailgun fixture

The wizzard of Fuel UI is defined within nailgun fixture(newrelease.yaml)
while a standard fuel plugin can only add additional sections to setting tab.

FPB postinstall hook could be the best way to deploy newrelease.xml,
but this feature will be delivered with MOS Fuel 7.0. And now deploy.sh
will do this work temporarily.

Moreover nailgun database will constrain the combination of the name
and version of new release but cannot, by far, delete the old version.
This function is included in cleardb.py and invoked by deploy.sh.
