devstack: Allow 3rd party neutron backends deployment

Browse Source 
In plugin.sh, there is only support for neutron reference
implementation, with either openvswitch or linuxbridge agent.

This change allows external devstack plugins to define hooks needed in
devstack.

Added hook to plugin.sh: `octavia_create_network_interface_device` and
`octavia_delete_network_interface_device`. For each of these functions,
if they are defined during stack (respectively unstack), they are called
to create (respectively delete) the management network interface.
