Default value for "of_interface" config option was switched
to "native" in Pike release.
In the same release this option was deprecated to removal.
Now it's time to remove it and force use of "native" driver to
manage openflows.

Since Pike log messages should not be translated.
This patch removes calls to i18n _LC, _LI, _LE, _LW from
logging logic throughout the code. Translators definition
from neutron._i18n is removed as well.
This patch also removes log translation verification from
ignore directive in tox.ini.

Other than the of_interface methods, today we are forced to use ovs_lib
methods to program flows, which call ovs-ofctl in turn. Let's make
install_instructions accept string actions regardless of of_interface
driver.

With this change the delete_flow variant implementation
of OpenFlowSwitchMixin, which was overriding the parent implementation
from ovs_lib in an incompatible way using the native ryu implementation,
is renamed into uninstall_flows.
As discussed in bug 1628455, the approach consisting in
extending the _keyword dict to convert ovs-ofctl rules into ryu
parameters does not seem practical.
This change also updates calls to delete_flows so that, when
enabled, the native interface will be used. Similar calls outside neutron
repo need to be updated as well, which will be done in separate changes.

With this change calling delete_flows with no kwargs will (instead
of resulting in calling "ovs-ofctl <action> <bridge> -", which does
nothing with no flow spec given on stdin) result in calling
"ovs-ofctl <action> <bridge>", which will delete all flows.
This aligns the behavior of delete_flows with the behavior currently seen by
all callers for the same method shadowed by the implementations in
OpenFlowSwitchMixin classes.

- Introduces an API to allow l2-agents to access resources within
the Open vSwitch Agent, specifically the integration and tunnel bridges.
- adds consume_api method to the AgentCoreResourceExtension class.
- modifies the AgentExtensionManager class to accept the AgentExtensionAPI
class as an optional argument.
- adds the OVSAgentExtensionAPI class.
- modifies ovs_lib and ofswitch to include a list of uuid stamps
to exempt from flow deletion.
- adds the OVSBridgeCookieMixin class that manages the distribution of
cookies and maintains the list of reserved cookies.
- modifies OVSNeutronAgent to initialize OVSAgentExtensionAPI and pass
into the AgentExtensionManager.

- This does NOT break other projects that rely on neutron.i18n,
as this change includes a debtcollector shim to maintain those
older entry points, until they can migrate.
- Also updates _i18n.py to the latest pattern defined by oslo_i18n
- Guidance and template are from the reference:

Without that fix flows applied to br-tun through
DeferredOVSBridge are created without cookie.
That results in l2pop flows being deleted in the process of
cleanup of stale flows.
Solution is to add cookie to all add/mod-flows of OVSBrigde
class in the method do_action_flows.
Also, agent_uuid_stamp moved to a proper place - into the
base OVSBridge class as storing attributes in Mixing was
just a wrong code design.

Closes-Bug: #1489372
When agent is restarted it drops all existing flows. This
breaks all networking until the flows are re-created.
This change adds an ability to drop only old flows.
Agent_uuid_stamp is added for agents. This agent_uuid_stamp is set as
cookie for flows and then flows with stale cookies are deleted during
cleanup.

This commit moves the L2 agents (Linuxbridge and OVS) into the
ML2 directory, while at the same time also moving the ML2 server
bits into toplevel directories. It also moves the configuration
files and unit tests. We also move the l2pop RPC mixin while
here as well.
