Add default route to dhcp agent netns.

Remove code block "if self.conf.enable_metadata_network:". No need to treat it
differently. Default route will be set as any other network.

defer firewall updates to iptables data structures

One of two patches that fixes bug #1194438.

In the iptables firewall driver, each port method (update_port_filter,
prepare_port_filter, remove_port_filter) makes O(N) calls, where
N=len(firewall.ports), to IptablesManager methods that update dozens
of data structures. When the firewall methods are called in sequence,
e.g., by SecurityGroupAgentRpcMixin, the calls to IptablesManager's
methods start to add up.

This patch changes IptablesFirewallDriver to defer and coalesce calls
to IptablesManager. Now a sequence of M port method calls results in
O(N) calls to IptablesManager methods instead of O(N*M) as before.

Firewall as a Service (FWaaS) APIs and DB Model

Implements: blueprint quantum-fwaas

blueprint: quantum-fwaas-plugin

This is the first iteration of the FWaaS implementation and
is geared towards implementing the model that will be
required to at least address the reference implementation.

This iteration will not include implementation of the following
features:
* grouping or dynamic objects
* application/service objects

Separate NVP create lport operation and neutron db transaction

Bug 1200001

This patch removes the NVP call for creating a logical port from
the SQL transaction context used for creating the Neutron port.
It also ensures orphaned data are properly removed from both
the Neutron DB and the NVP backend.

Make NEC Plugin keep error resources

NEC Plugin used to ignore OFC errors while deleting resources from OFC,
and it could leave some unused resources on OFC. If OFC generates id
which is in remained resources when creating new resource, it will fail.

This commit makes NEC Plugin keep logical resource when it failed to
delete resource from OFC not to leave orphan resource on OFC, and raise
exception to tell the user that the resouce status is Error.

NOTE: The user can retry deletion. If the resouce was successfully
deleted from OFC in retries, the logical resource will be deleted.
