Add "--network-segment" option to the "subnet create" command. This is a beta command option and subject to change. Use global option "--os-beta-command" to enable this option. This patch set also provides a devref update for beta command options. Change-Id: I4d0fbe079b2a873307364c41c22ce9ba88e632e6 Partially-Implements: blueprint routed-networks

Command Beta

============

|
|
|
OpenStackClient releases do not always coincide with OpenStack
|
|
releases. This creates challenges when developing new OpenStackClient
|
|
commands for the current OpenStack release under development
|
|
since there may not be an official release of the REST API
|
|
enhancements necessary for the command. In addition, backwards
|
|
compatibility may not be guaranteed until an official OpenStack release.
|
|
To address these challenges, an OpenStackClient command may
|
|
be labeled as a beta command according to the guidelines
|
|
below. Such commands may introduce backwards incompatible
|
|
changes and may use REST API enhancements not yet released.
|
|
This also applies to command options associated with the beta
|
|
command object.
|
|
|
|
See the examples below on how to label an entire command or
|
|
a specific option as a beta by updating the documentation
|
|
and implementation.
|
|
|
|
The initial release note must label the new command or option
|
|
as a beta. No further release notes are required until the command
|
|
or option is no longer a beta. At which time, the beta label or
|
|
the command or option itself must be removed and a new release note
|
|
must be provided.
