Bug Description

When neutron-api is set to use DVR:

neutron-api:
 openstack-origin: cloud:trusty-liberty
 neutron-external-network: "ext-net"
 neutron-security-groups: true
 enable-dvr: true
 network-device-mtu: 9000
 overlay-network-type: vxlan

 with neutron-openvswitch and neutron gateway configured this way:

 neutron-gateway:
 openstack-origin: cloud:trusty-liberty
 ext-port: eth1

neutron-openvswitch:
# enable-local-dhcp-and-metadata: true
 ext-port: eth1

 nova-compute ends with neutron-openvswitch installed, but the neutron-openvswitch charm installs and then subsequently uninstalls the neutron-l3-agent (twice):

2015-11-10 08:39:52 INFO neutron-plugin-relation-changed The following extra packages will be installed:
2015-11-10 08:39:52 INFO neutron-plugin-relation-changed conntrack iputils-arping ipvsadm keepalived libdaemon0 libperl5.18
2015-11-10 08:39:52 INFO neutron-plugin-relation-changed libsensors4 libsnmp-base libsnmp30 neutron-metadata-agent radvd

...

2015-11-10 08:40:04 INFO neutron-plugin-relation-changed neutron-l3-agent* neutron-metadata-agent*

...

2015-11-10 08:40:26 INFO neutron-plugin-api-relation-changed The following NEW packages will be installed:
2015-11-10 08:40:26 INFO neutron-plugin-api-relation-changed neutron-l3-agent neutron-metadata-agent

...

2015-11-10 08:40:32 INFO neutron-plugin-api-relation-changed The following packages will be REMOVED:
2015-11-10 08:40:32 INFO neutron-plugin-api-relation-changed neutron-l3-agent* neutron-metadata-agent*

This results in inability to create VM, since the L3 agent is missing on the compute nodes.

Working on reproducing this issue now; I think this may be caused by the new enable-local-dhcp-and-metadata which will uninstall the metadata-agent if not enabled; this results in the l3-agent being un-installed as well as it depends on the metadata-agent.

Proposed branch works for me; just waiting for CI wheels to spin and we'll get it landed and start the backport for stable.
