The concurrent.futures module is one of the ways that async activities can be done in the future, so we should try to work on getting to that future by using more futures. To enable this (as well as to enable getting off eventlet), add a thread pool based executor which will process incoming messages using the pool. Also begins adding according docs as well for the different types of executors that are available. Change-Id: I1482fd70abbf69f4e2994597c5e95d91fecb815e

|
|
|
|
The returned list includes all oslo.config options which may be registered
|
|
at runtime by the library.
|
|
|
|
Each element of the list is a tuple. The first element is the name of the
|
|
group under which the list of elements in the second element will be
|
|
registered. A group name of None corresponds to the [DEFAULT] group in
|
|
config files.

|
|
|
This function is also discoverable via the 'oslo.messaging' entry point
|
|
under the 'oslo.config.opts' namespace.

The purpose of this is to allow tools like the Oslo sample config file
|
|
generator to discover the options exposed to users by this library.
