Hi folks,

I'd like to present blueprint
I feel needs to be in grizzly.
You can find more detailed description in specification page.

Initially we planned to have comprehensive device management as separate
plugin with extension and complicated schedulers.
However due to the lack of time and reviewer resources we desided to
greatly reduce the scope of this work.
So, currently the code on review ( https://review.openstack.org/#/c/20225/ )
introduces the following:
1) Configuration management for service schedulers, e.g. admin can
configure particular scheduler for particular service type
2) Simplistic scheduler for lbaas:
  - scheduling algorithm that randomly chooses a device from list of devices
  - device manager that reads devices from predefined conf-file (suggestion
from Salvatore)

I believe this is reasonable minimum that will allow to use LBaaS service
at least with some convenience.
(In fact, I'd provide some more scheduling algorithms)

We have also started to integrate this code with code of
to the call sequence diagram:
So we plan that this code will be base patch for
