consider install utility inside python package

[Cedev]

What would the install utility do?

• Add the service_provider line for LOADBALANCER/LOADBALANCERV2 to neutron.conf or neutron_lbaas.conf?
• Add either neutron.services.loadbalancer.plugin.LoadBalancerPlugin or LoadBalancerPluginv2 to service_plugins?
• Create /etc/a10/config.py if it doesn't exist?
• Run the database migrations?
• A tool to reload the q-svc and either q-lbaas or q-lbaas2?
• A tool to reload /etc/a10/config.py (reloading the services seems more openstack-y)?

• Create Nova flavors for acos devices?
