Fix passing keystone token to neutronclient instance

Neutron client expects token to be passed as token= argument, while
neutron-metadata-agent passes auth_token= instead. This effectively makes the
client to authenticate against keystone each time it's instantiated. In
neutron-metadata-agent case, it means 'each time a client sends a metadata
request.'

The issue results in high cpu utilization on keystone side when simultaneously
invoking multiple nova instances with cloud-init.

NSX plugin: fix floatingip re-association

The NSX plugin does not allow to reassociate a floating IP to
a different internal IP address on the same port where it's
currently associated.
This patch fixes this behaviour and adds a unit test to ensure
re-association on the same port with a different IP is possible.

A few tweaks to the unit test aux functions were necessary to
accomodate the newly introduced unit test.

Merge "ML2 Cisco Nexus MD: Create pre/post DB event handlers"
Add migration support from agent to NSX dhcp/metadata services

This is feature patch (3 of 3) that introduces support for
transitioning existing NSX-based deployments from the agent
based model of providing dhcp and metadata proxy services
to the new agentless based mode. In 'combined' mode, existing
networks will still be served by the existing infrastructure,
whereas new networks will be served by the new infrastructure.

Networks may be migrated to the model using a new CLI tool
provided, called 'neutron-nsx-manage'. Currently the tool
provides two admin-only commands:

  neutron-nsx-manage net-report <net-id-or-name>

This will check that the network can be migrated and returns
the resources currently in use. And:

  neutron-nsx-manage net-migrate <net-id-or-name>

This will move the network over the new model and deallocate
resources from the agent. Once a network has been migrated
there is no turning back.
