LBaaS: make device driver decide whether to deploy instance
Currently server throws an error in case agent (device driver)
requests logical config for non-active pool, which is a bug
as it's ok if pool is in pending create/update states.
Also the pool may be already scheduled for delete (pending_delete)
while agent requests it to perform some previous update, which
as also ok and agent just doesn't deploy such config.
This patch moves active pool check from server side to agent side

NEC plugin: Remove a colon from binding:profile key due to XML problem
In XML specification, if a tag name contains a colon, a part before
a colon is interpreted as namespace. If key names in binding:profile
dict contains a colon, Neutron XML serializer sends them as-is.
A colon in key names should be used only if XML namespace are used.
NEC plugin uses a colon in key names and it leads to failures to XML
deserialization. To avoid this problem, this commit removes a colon
and prefix n key names in port binding:profile so that client XML
deserializer decodes XML response successfully.

Instead of returning exception specific to haproxy (agent-based),
return more generic BackendNotFound exception.
It also could be used later when binding to devices will be
introduced. That exception will indicate scheduling failure, e.g.
inability to find appropriate backend for the resource.
Resource (pool) is then marked with ERROR state with corresponding

This commit [1] changed the behavior of modifying flows to not allow priority

this regard. I've corrected this behavior now, and added a negative UT case to

ML2: Remove validate_port_binding() and unbind_port()
The API implemented by ML2 mechanism drivers included three methods
related to port binding that were called within DB transactions, but
that could potentially involve communication with controllers or
devices that should not be done within transactions. A subsequent
patch will move the calls to bind_port() outside of tranactions. This
patch eliminates the other two methods from the MechanismDriver API.
The validate_port_binding() method was previously called on the bound
mechanism driver to check whether an existing binding was still valid,
so that the port could be rebound if something changed. But since nova
has no way to handle changes to binding:vif_type or
binding:vif_details after a port is initially plugged, this turned out
not to be useful, so the method has been removed from the
MechanismDriver API. Now, once a port is successfully bound, the
binding remains until the port is deleted or any of it's
binding:host_id, binding:vnic_type, or binding:profile attribute
values are changed.
The unbind_port() method was previously called on the bound mechanism
driver as an existing binding was removed. This method was not used by
any existing mechanism drivers, and was redundant with the
update_port_precommit() and update_port_postcommit() methods that are
called on all mechanism drivers when an existing binding is removed,
so this method has also been removed from the driver API.
Eliminating the unbind_port() call allows the binding details to be
made available via the PortContext in delete_port_postcommit() calls,
completing the resolution of bug 1276395.

Fix duplicate name of NVP LBaaS objs not allowed on vShield Edge
Duplicate name of LBaaS objs such as pool/vip/app_profile is not
allowed on vShield Edge, so here a name convention is needed to ensure
name uniqueness on the edge side.
Closes-Bug: #1257225
This patch adds a semaphore for serializing the delete port API
calls and update_port_status calls to avoid simultaneous
attempts to acquire SQL update locks on the port table from
the same thread pool.
This semaphore has been introduced to avoid undesired eventlet
yields which trigger 'lock wait timeout' errors in the DB backend;
it should have a negligible impact on the overall performance.

Enable to select an RPC handling plugin under Metaplugin
Multiple plugins under metaplugin become 'q-plugin' topic
consumers and a request from an agent is handled by one of
them randomly. Fortunatly most of RPC callbacks are common
for plugins but a problem occurs if an RPC is not supported
by the received plugin.
This is one of risks when using metaplugin. Fundamental fix
of this problem (such as RPC delegation handling of metaplugin)
is difficult since each plugin needs to modify.
But when only one plugin has plugin specific RPCs and other
RPCs are independet of plugins, if the plugin can be selected
for RPC handling, the problem does not happen. Typical use
case of metaplugin such as combination of an agent-based
plugin and a controller-based plugin often applies to this
condition.
This patch adds 'rpc_flavor' configuration parameter to
select an RPC handling plugin. If 'rpc_flavor' is specified,
only the specified plugin becomes 'q-plugin' topic consumer.
If 'rpc_flavor' is not specified, the behavior is same as
previous one.
