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.

Neutron lib now contains ServicePluginBase [1]. In accordance
with the discussion in [2], this patch:
- Removes ServicePluginBase from neutron and replaces all uses
with neutron-lib.
- Removes PluginInterface; the plugin interface for extensions
is ServicePluginBase; that's what's used by everyone today.
- Updates a few UTs, based on the above.
NB: A subsequent patch will address the WorkerSupportServiceMixin
so its untouched herein.

This reverts commit b1cdba1696
Original patch was reverted because it broke neutron plugin's
backward compatibility and needed more work.
This patch fixes that problems:
1) original behaviour of add_agent_status_check,
start_periodic_l3_agent_status_check and
start_periodic_dhcp_agent_status_check methods is deprecated but kept
for using in third part plugins for backward compatibility
2) new add_agent_status_check_worker, add_periodic_l3_agent_status_check
and add_periodic_dhcp_agent_status_check method are implemented
instead and are used for implementing plugins in neutron codebase

I think this needs a little more thought. This broke OVN at least and
I don't think that's good. We need to figure out how to be compatible
with existing plugins, even out of tree ones.
This reverts commit 1cafff0871.

Forking a process when multiple threads are running is an unsafe
operation and could cause a lot of problems because only current
thread will continue working in child thread. Any locked by other
thread resource will remain locked forever.
We faced with this problem during oslo.messaging development and
added workaround to hide this problem:
https://review.openstack.org/#/c/274255/
I tried to fix this problem in oslo.service:
https://review.openstack.org/#/c/270832/
but oslo folks said that this fix is ugly and it is wrong way to add
workarounds to common libraries because projects use them incorrectly.
I think that is fair.
So this patch fixes incorrect usage of oslo libraries. In this patch
I extended functionality of NeutronWorker and add there
`worker_process_count` parameter which determines how many processes
should be spawned for this worker. If `worker_process_count` = 0 - don't
create process and spawn thread in scope of current process for worker
Then I moved all background tasks to workers and return them by
`get_workers` method. start_plugin_workers collects plugin's workers
using `get_workers` method and starts in ProcessLauncher first workers
with `worker_process_count` > 0 and only after this starts threaded
workers by simple Launcher

- 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:

There are several cases where plugin initialization should be
handled after neutron-server forks API/RPC workers. For example,
starting a client connection to an SDN controller before forking
copies the fd of the socket to the child process, but then you have
multiple processes trying to read/write the same socket connection.
It is also useful for a plugin to be able to do something in only
one process, regardless of how many workers are forked. One example
would be handling syncing from an external system to the neutron
database.
This patch does 3 things:
1) Treats rpc_workers=0 as = 1. This simplifies the code for
handling notification that forking has completed. In the
existing code, calling the notification in the Worker object's
start() method would happen twice in the case where both api
and rpc workers were 0, despite there being only one process.
An earlier patch already changed the default api_workers to be
the number of processors.
2) Adds notification of forking via the callbacks mechanism.
Plugins can subscribe to resources.PROCESS, event.AFTER_CREATE
and do any post-fork initialization that needs to be done for
every spawned process.
3) Adds core/service plugin calls to get_workers() which defaults
to returning (). Plugins that need additional processes to spawn
should just return an iterable of NeutronWorkers that will be
spawned in their own process.

last usage is: 1b36e20771

It's mostly a matter of changing imports to a new location.
Non-obvious changes needed:
* pass overwrite= argument to oslo_context since oslo.log reads context
from its thread local store and not local.store from incubator
* don't store context at local.store now that there is no code that
would consume it
* LOG.deprecated() -> versionutils.report_deprecated_feature()
* dropped LOG.audit check from hacking rule since now the method does
not exist
* WritableLogger is now located in oslo_log.loggers
Dropped log module from the tree. Also dropped local module that is now
of no use (and obsolete, as per oslo team).
Added versionutils back to openstack-common.conf since now we use the
module directly from neutron code and not just as a dependency of some
other oslo-incubator module.
Note: tempest tests are expected to be broken now, so instead of fixing
all the oslo.log related issues for the subtree in this patch, I only
added TODOs with directions for later fix.

Oslo project decided to move away from using oslo.* namespace for all their
libraries [1], so we should migrate to new import path.
This patch applies new paths for:
- oslo.config
- oslo.db
- oslo.i18n
- oslo.messaging
- oslo.middleware
- oslo.rootwrap
- oslo.serialization
- oslo.utils
Added hacking check to enforce new import paths for all oslo libraries.
Updated setup.cfg entry points.
We'll cleanup old imports from oslo-incubator modules on demand or
if/when oslo officially deprecates old namespace in one of the next
cycles.

Mostly trivial import changes.
- oslo.i18n no longer provide install() method to inject _() into
globals(), so removed all calls to it;
- removed Babel from dependencies (it will now be grabbed by oslo.i18n);
- updated tox.ini to ignore import violations for oslo.i18n.

Don't log the error using LOG.error or LOG.exception and then
passing the same string to SystemExit since this will result in the

The patch makes the following changes:
* adds new attribute of the pool: provider, which is provider name
as it is written in configuration
* adds support for multiple plugin drivers for loadbalancer
* cleans up healthmonitor-related plugin driver API
Drivers should work with healthmonitor associations only
* adds ability to update provider attribute for the pool used
to reassociate pools with new providers in case their providers
were removed from configuration
