Title:
Openstack add 'deafult' security group to a VM when attaching new
interface to new network even the VM have customized secgroup
Status in neutron:

Bug description:
I am not sure if its design intention, Openstack add 'deafult' security group
to a VM when attaching new interface to that VM even if the VM have customized
secgroup .
for many deployment, users create and add customized security group to
the VMs, so when attaching new network interface to the VM, Openstack
keeps the customized secgroup , but in addition, it adds the 'deafult'
which is not good as default should not have all security ports open
by default.
Liberty,
before attach the VM to new network < Nova show <vm> >
| security_groups | customized
|
after VM attached to new network < Nova show <vm> >
| security_groups | customized, default
|
