Kailun Qin a01b7125cd Use network segment ranges for segment allocation
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
- 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.

Boden R 95f1e03446 use plugin constants from neutron-lib
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.

Inessa Vasilevskaya 7322bd6efb Make code follow log translation guideline
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.

Aradhana Singh 62fd09afc7 Refactoring config options for ml2 plugin drivers
Refactoring neutron ml2 drivers configuration options to be in
neutron/conf/plugins/ml2/drivers. This would allow centralization of
all configuration options and provides an easy way to import.

Doug Wiegley dd726ed494 Move i18n to _i18n, as per oslo_i18n guidelines
- 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 to the latest pattern defined by oslo_i18n
- Guidance and template are from the reference:

Martin Hickey 71190773e1 Automatically generate neutron core configuration files
This adds a new tox environment, genconfig, which generates sample
neutron core configuration file using oslo-config-generator.

Updates to some configuration option help messages to reflect useful
details that were missing in the code but were present in config files.

It also adds details to devref on how to update config files.

Aaron Rosen 7b7c15ba4e Add Geneve type driver support to ML2
More information about Geneve protocol can be found here:

Following configuration variables were added:
  vni_ranges - Comma-separated list of <vni_min>:<vni_max> tuples
               enumerating ranges of Geneve VNI IDs that are
               available for tenant network allocation
  max_header_size - Geneve encapsulation header size is dynamic, this
                    value is used to calculate the maximum MTU for the driver
                    this is the sum of the sizes of the outer
                    ETH + IP + UDP + GENEVE header sizes
