BigSwitch: correct net to backend on floating IP disassociation
The corrects the network that is updated on the backendw when a
floating IP is disassociated. It was incorrectly sending the
tenant's network when the update is to the external network the
floating address belongs to.
Add a route to reach the MD server when a subnet is created
When the first subnet is created, the dhcp port is created and
midonet plugin correctly adds the static route to reach the MD
server in create_port. When a second or following subnets are
created, a new ip is added to the dhcp port. This patch takes
care of adding the static route to correcly reach the MD server
in update_port. This fixes the problem of VMs not being able to
reach the MD if assigned to the second subnet
This patch adopts several measures to prevent _sync_routers_task
and _rpc_loop from hanging because of subprocess.Popen.communicate
not returning.
1) Perform a sleep everytime a command is completed, similarly to
what is done in openstack.common.processutils.execute
2) Disable by default GARP, as kernel crashes caused by arping
have been observed
3) Prevent a non-critical keyerror in _router_removed from triggering
again a full sync, which might put the system under significant load.
This patch also adds debug log statements aimed at improving the
ability of debugging similar failures.

Avoid race with udev during ovs agent startup
After taking down the veth link between the physical bridge and the integration
bridge call udevadm settle to wait for any udev events to be completely
processed by the operating system before recreating the veth pair.
Some distributions (e.g. openSUSE) have udev rules installed by default that
call e.g. ifdown <interface> during the remove event. If that is processed
after the ovs agent already brought up the veth pair again the veth pair's
link will be down after the agent completed startup and networking will be
broken for all VM instances.
Quota driver is now loaded in lazy mode, i.e. the driver is loaded
the first time the driver is accessed. This is to make unit tests
work. Some unit tests like extension test cases need to use Config
Quota driver (previous default) but QuotaEngine is initialized
when quota.py is imported. Thus the unit tests had no chance to
specify quota_driver.

Disable lazy translation
Late in the Havana cycle bug 1225099 was found in the lazy
translation code, and to be safe it was decided to disable lazy
translation for Havana. This change does that.
Cisco plugin should check for switch - vlan bindings
This commit fixes the issue where the Cisco plugin tries to create a
vlan twice on a switch if the first create is not bound to a port.
Also fixes an issue where the plugin tried to untrunk vlans from
a port for SVI interfaces.
Should not add metadata filter rules if disable metadata proxy
The metadata filter rules should not be added into iptables if Neutron
metadata proxy is disabled.
This patchset fixes this issue by adding a condition when adding metadata
filter rules to iptables.

Fix auto-deletion of ports and subnets in ML2
When a network is deleted, certain ports and any subnets referencing
it are auto-deleted. The implementation of
NeutronDBPluginV2.delete_network() does this at the DB level, so ML2's
mechanism drivers were not being called.
Ml2Plugin.delete_network() is changed to not use the base class's
method, and to auto-delete ports and subnets by calling its own
delete_port() and delete_subnet() methods outside of the
transaction. A loop avoids race conditions with ports or subnets being
asynchronously added to the network.
Fix to enable delete of firewall in PENDING_CREATE state
Firewall will in PENDING_CREATE state if there is no underlying router in the
tenant. When the router and an associated i/f is created then with a sequence
of msgs it is set to ACTIVE state by the plugin. If a delete is triggered when
in PENDING_CREATE state in such a situation, the msg was ignored - fixing this to
account for the fact that a delete makes sense in this situation so the agent
sends the appropriate msg back to the plugin so it can delete it.

Reverse the order of interface update and DNAT rule config
Configure DNAT rule first before adding floating ip address to interface
so advanced service router will not receive packets by accident before
DNAT rule configured.
Verified that traffic goes to the VM the created floating ip associated
with right after config.
IF both service neutron-l3-agent and neutron-server are up,
but no router id configured in /etc/neutron/l3_agent.ini, an
exception will be raised on DB as "DBError: IntegrityError",
because the variable router_ids has a default '' value that
doesn't match the DB grammar.
* Check router id is specified in _init_() of l3 when
not using namespace.
* Move part of checking config params actions to new function
_check_config_params()
* Add corresponding unit tests.
Redefine behavior for NvpAdvancedPlugin during network creation
When using the NvpAdvancedPlugin, *all* logical switches should
be created through VCNS. VCNS will then proxy the requests to
NVP. This patch implements such a behavior. This is achieved by
replacing the use of nvplib.create_lswitch with the one of the
vcns driver, as the remaining logic can be left as it is.

This patch adds an option for always synchronizing operational status

Ensure router exists when auto_schedule_routers
Currently, the auto_schedule_routers() accepts parameter router_ids,
which may contain invalid router ids, since we've already filtered
them via plugin.get_routers(), we can directly use that safe object.
Properly synchronize status for ports deleted from backend
Ensure that the status for a port is properly synchronized even
when the port itself does not exist anymore in the backend, avoiding
raising exceptions due to missing results in the NVP query.

From the initial commit of NEC plugin, network_id of packetfilters
table is nullable=False, but in folsom_initial db migration script
nullable is set to True. This commit ensure nullable=False for
