Call _allocate_vr_id outside of transaction
_allocate_vr_id is called from _set_vr_id, which was starting a
transaction before calling it. This caused an error when the retry
logic was triggered inside of _allocate_vr_id since it would
encounter a DB exception and put the transaction into a bad state
that couldn't be used on the retry.
This patch just stops _set_vr_id from starting a transaction because
it didn't serve a purpose. It also stops _allocate_vr_id from allowing
subtransactions when it starts a transaction, since it's retry logic
isn't compatible with them.

DVR:Fix _notify_l3_agent_new_port for proper arp update
Now with notifications coming from ml2 plugin on port create
and port update, it is worth fixing the existing _notify_
l3_agent_new_port for proper arp update and router scheduling.
Previously we have been sending arp update and calling router
scheduling for every update notification for service ports,
but now we can take necessary action only when required, since
the fix to update the arp and router scheduling was recently
done by sending the port info for every new port created.
When _notify_l3_agent_port_update is triggered, we check if the
original port host binding exists and if there is a change in
host binding with respect to the new port, then we go ahead and
reschedule the router on the new host and flush the arp entry.

Force L3 agent to resync router it could not configure
If the L3 agent fails to configure a router, commit: 4957b5b43521a61873a041fe3e8989ed399903d9 changed it so
that instead of performing an expensive full sync, only that
router is reconfigured. However, it tries to reconfigure the
cached router. This is a change of behavior from the fullsync
days. The retry is more likely to succeed if the
router is retrieved from the server, instead of using
the locally cached version, in case the user or operator
fixed bad input, or if the router was retrieved in a bad
state due to a server-side race condition.
Note that this is only relevant to full syncs, as those retrieve
routers from the server and queue updates with the router object.
Incremental updates queue up updates without router objects,
so if one of those fails it would always be resynced on a
second attempt.

Enable Guru Meditation Reports for other refarch agents
OVS agent already supports GMR, but LinuxBridge and SR-IOV agents don't.
To enable them for those agents, we should move their main() entry
points under neutron/cmd/, so that __init__.py code that initializes
them is triggered on their invocation.
Since we put their entrypoints under neutron/cmd/eventlet/, there is now
also no need to explicitly monkey patch stdlib for eventlet in the
agents code (neutron/cmd/eventlet/__init__.py already does it for us).
With that, there is no more code in the tree that directly patches
stdlib except neutron/cmd/eventlet/__init__.py.
Also removed a way to execute agent modules as scripts since it's not a
supported way to invoke them (instead, stevedore generated console
scripts should always be used).

Use a joined relationship for AZ info on routers
This patch adds a joined relationship from the routers

agent availability zones during router listings.
This fix is the same as the one for networks here:

A follow-up patch will add an AZ table so this doesn't
have to join directly to the agents table.
Right now we have seen some performance issues when
dvr routers are scheduled on multiple compute nodes
with thousands of VMs on the routed subnets.
The _get_candidates call get_l3_agent_candidates with
a complete list of agents irrespective of the routers
already hosted on the agents or not.
So this fix will reduce the amount of iterations that
get_l3_agent_candidates need to process for all the
agents and would increase the control plane performance.
This fixes an issue where the lb agent did not plug the
dhcp tap device into the bridge when having vlan networking
set up. Caused by setting of disable_ipv6 value.

Adding a VNIC type for physical functions

The new VNIC type 'direct-physical' deviates from the behavior of

as a port, it does not currently perform any management functions.
Future changes may extend the segment mapping functionality that is

the other SR-IOV VNIC types in that quality of service and port security
functionality is not available.
