This patch makes necessary changes to ML2 type drivers and plugin
manager for network segment range extension support when it is loaded.
When the network segment range extension is not loaded, no impact to the
current flow.
When the extension is loaded,
- populating a range that is managed from the configuration file [1]_,
such as "VLAN IDs", "VXLAN VNI IDs", "GRE tunnel IDs",
"Geneve VNI IDs" to the network segment range DB table as a "default"
and "shared" entry to maintain backward compatibility;
- reloading the "default" segment ranges when Neutron server
starts/restarts;
- creating a set of "default" network segment ranges out of the
ML2-config-file-defined ranges [1]_ and the segment allocation
operations are always retrieving the information from the DB to have
the network segment ranges fully administered via API;
- when a tenant allocates a segment, it will first allocate from an
available segment range assigned to the tenant, and then a shared
range if no tenant specific allocation is possible.

The ml2 plugin driver API was rehomed into neutron-lib with commit
Ifc829953ef4d5859c3475903965dc08aba42fd9c and the API was shimmed in
neutron with I86a10091b55d1123e8d16f16155e0312bb10e54c. This patch
consumes the ML2 driver api from neutron lib thereby removing the
driver_api module from neutron.

neutron-lib contains a number of the plugin related constants from
neutron.plugins.common.constants. This patch consumes those constants
from neutron-lib and removes them from neutron. In addition the notion
of the dummy plugin service type is moved strictly into the test
package of neutron since it's not a real service plugin.

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.

The ml2 MechanismDriver is now in neutron-lib along with its associated
constants. This patch switches over to the lib versions of those, but
leaves a shim of the MechanismDriver that just ref's the driver from
lib. This shim allows our broad consumer base of the driver to switch
over at their leisure.

according to https://wiki.openstack.org/wiki/Python3,
now we should avoid using six.iteritems and replace
it with dict.items.

We have a number of functions that expect to get session as one
of the arguments. Passing session is not correct and this prevents
of using new enginefacade which expects context to be passed and
session will be injected in current context.

- 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:

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.

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.

All the existing LOG.info, LOG.warning, LOG.error and LOG.critical
messages should have _LI, _LW, _LE and _LC respectively.
Also, debug level log shouldn't be translated.
This patch set will cover the ml2 directory under neutron/plugins.

ML2 provider network partial specs let admins choose some
multiprovider network attributes and let neutron choose remaining
attributes. This change provides the implementation for
multiprovider networks.
In practice, for VLAN/GRE/VXLAN segments provider:segmentation_id
choice can be delegated to neutron, in such case neutron try to find
a segment in tenant network pools which respects provided segment
attributes. For VLAN segments provider:physical_network choice can
also be delegated.

This patch removes new definitions of common network type constants (TYPE_FLAT,
TYPE_LOCAL, etc.) and modifies uses of aforementioned constants to a common
place where constants are defined (neutron.plugins.common.constants). This
patch does not change values that are equal in value but different in name:
NETWORK_TYPE_FLAT vs TYPE_FLAT. A second changeset will be made to handle that
case.
Unit tests were modified as well when they referred to the constant.
Finally, the ovs agent code refers to the OVS plugin constants directly and
these had to be changed as well. A TODO flag was put in that file due to use
of another plugin specific constant.
Network types that were only defined in a single plugin, such as mellanox's
infiniband (IB) network type was not carried over to the common constants file.
