Remove the neutron-grenade job definition

All the user of neutron-grenade from Ussuri gate
onwards has been switched to grenade-py3 job (except
neutron which is running neutron-grenade-multinode).

We can remove the job definition also now and all
stable gate using this job will find the job definition
from neutron stable branches.
