Stop logging unnecessary warning on context create
The context was previously logging at the 'warn' level when unknown
kwargs were being passed to its __init__(). Since the agents were
passing tenant=None with each rpc request, this was generating an
unreasonable amount of log chatter that would not be useful to an
operator. The fix is to log at the debug level instead so that
the operators don't see the output by default but developers can
still choose to.

Avoid dhcp agent race condition on subnet and network delete
Ensure that ports that are about to be deleted are 'selected
for update'. By doing so, we avoid a race condition between
subnet and network delete operations carried out by two
separate server instances.
A race caused by the dhcp agent deleting the DHCP port
(caused by a subnet-delete event notification) can
still occur and will be addressed in a subsequent patch.
delete_subnet's way to delete ports has been tweaked to
ensure that postgres db can handle the SELECT FOR UPDATE

ML2 plugin should not delete ports on subnet deletion
On subnet deletion ports are deleted asynchronously by dhcp agent
so plugin doesn't need to delete them itself.
Instead Ml2Plugin.delete_subnet() method should call update_port()
for each allocation to remove the IP from the port and call the MechanismDrivers.
The patch also adds subnets test suite from test_db_plugin to test_ml2_plugin.
Handle IPAddressGenerationFailure during get_dhcp_port
If a network/subnet is deleted while the dhcp agent is trying
to get/create a dhcp port for that network, the exception
will be raised because no IP Allocation Range is available.
However, this particular failure mode causes just noise, because
the dhcp agent can cope with it without problems.
A follow-up patch will deal with the other exception traces during

Added check on plugin.supported_extension_aliases
Added check to neutron.api.extensions.PluginAwareExtensionManager
which raises an exception when an alias in the plugin's
`supported_extension_aliases` list is not found in the set of loaded
extension aliases. If an alias is missing, it means the extension for
that alias has not been loaded, has not been found, and the file is
missing from paths listed in `oslo.config.CONF.api_extensions_path`.
This guards against a common class of bugs in plugins,
such as typographical errors in the `supported_extension_aliases`
property.
Plugin changes:
* bigswitch.plugin: Moves api_extensions_path override to plugin's
__init__ method, similar to other plugins.
* cisco.n1kv.n1kv_neutron_plugin: Removes "policy_profile_binding" and
"network_profile_binding" as they don't exist in Neutron currently.
Removed override of api_extensions_path as it is loaded through
cisco.network_plugin.
* cisco.network_plugin: Renames "Cisco Credential" to "credential".
Adds api_extension_path override to plugin's __init__ method.
* metaplugin.meta_neutron_plugin: Avoids alias of empty string when
cfg.CONF.META.supported_extension_aliases is an empty string.
Due to timing issues, when the agent synchronizes
with the server wrt the representation of server's
and agent's networks, networks may have already
been deleted from the db. In such circumstances,
it is more appropriate to emit warnings rather than
full-blown exceptions as the agent handles these
circumstances just fine.

NVP plugin:fix connectivity to fip from internal nw
The current set of NAT rules configured in the NVP logical router
prevents instances on an internal network from establishing TCP
connections with a floating IP associate with an internal port
on the same Neutron network.
This patch add a SNAT rule to ensure connections coming from the
internal network always appear to the port associate with the

This fix addresses improper behavior with the Cisco Nexus plugin's
selection of Nexus switch on which to place a Switch Virtual Interface
(SVI) when round-robin switch placement is enabled.
The expected behavior when round-robin SVI switch selection is configured
via the cisco_plugins.ini file, i.e.:
[cisco]
nexus_l3_enable = True
svi_round_robin = True
is that when a virtual router interface is created, the Nexus plugin should
select the Nexus switch with the least number of SVI interfaces configured
for creating the new SVI. The current selection is based on the first
entry in a dictionary, and is therefore indeterminate.
Similarly, this fix also addresses incorrect behavior when round-robin
selection is disabled. In this case, the desired behavior is that
the plugin should select the first switch which appears in the Nexus
switch configuration. Instead, the current selection is also based on the
first entry in a dictionary, and is likewise indeterminate.
Tune up report and downtime intervals for l2 agent
If the neutron server erroneously thinks than the l2 agent is down
it will fail to bind a port, which can lead to VM's spawn errors.
However, the issue is only transient because the agent effectively
is only 'late' in reporting back.
Best solution would be an alpha-count algorithm (so that we can detect
persistent failures more reliably), but for now let's be more tolerant
assuming that the agent is down by waiting at least twice the report
interval plus a tiny teeny bit.
The IntegrityError faced on network deletion that
spooks Tempest tests is most likely caused by the
fact that the ml2 plugin does a dirty read. By
adding a 'select for update' we should be able to
address the issue once and for all.
Also, there's a chance that the dhcp port gets
reallocated while we are deleting the network. To
this aim, catch the integrity error and attempt
to recover from it.
This patch also removes the handling of errors
on concurrent reads that can no longer occur when
deleting the network.
