vrouter inactive after delete and add back Compute node

[Sarath]

After delete and add-back the compute node, the vrouter not up on the compute node.

Thilak debugged my setup and found the issue is due to "/etc/init/supervisor-vrouter.override" getting created during delete of compute node. We verified when deleting this file and do add-back, it went fine... So, the issue is due to this.

Topology
##########

3 controllers (( Openstack + Contrail )
3 computes

Closes-Bug: #1535956
vrouter inactive after delete and add back Compute node

Issue:
service enable= false
was creating an override file while uninstalling roles.
as a result when the same role is added it doesnt start on boot.

Fix:
remove service enable = false as we are removing the packages when
we uninstall and the init scripts.

Testing:
1)remove and add roles to the same machine.
