Initial implemention of MetaPlugin

This plugin supports multiple plugins at same time. This plugin is for L3 connectivility
between networks which are realized by different plugins. This plugin add new attribute 'flavor:id'.
flavor:id correspond to specific plugin. flavor-plugin mapping could be configureable by plugin_list config.
This plugin also support extensions. We can map extension to plugin by using extension_map config.

Implements blueprint metaplugin

Adds the 'public network' concept to Quantum

Implements blueprint quantum-v2-public-networks

This patch allows Quantum to handle public networks. It modifies the
API adding a new attribute to the network resource ('shared')
and enhances the policy engine in order to handle the behaviour of
the service wrt shared networks.
Policy.json specifies a default behaviour which can be changed by
the administrator, even at runtime.
Tests added to test_db_plugin validate 'obvious' behaviour - such as
that only the ports belonging to a given tenant should be returned
even when they are queried on a public network.
Tests added to test_policy instead validate the changes added to the
policy engine.

improve test_db_plugin so it can be leveraged by extension tests

prereq for bp quantum-l3-fwd-nat

- load extension middleware as well as core API
- support 'action' requests in addition to CRUD ops
- add helper methods that check API return code
- clean-up places where existing tests where hitting 409s on delete
but ignoring the errors (basically SubnetInUse errors).

Fix bulk create operations and make them atomic.

Bug 1024844
Bug 1020639

The API layer is now able to issue bulk create requests to the plugin,
assuming that the plugin supports them. Otherwise, the API layer will
emulate atomic behavior.
This patch also implements OVS plugin support for bulk requests.

Add device_owner attribute to port

in order for firewall logic to be able to poke a hole allowing traffic to/from a DHCP server,
we need to expose the IP being used for DHCP in a subnet to external entities.
This commit adds device_owner attribute, then dhcp-agent will update the device_owner value
of port to dhcp-agent.

If we filter the fields of the requested resource, we have no parent_id in the target, which we must be tolerant with.
