Fix docs for REST API history and Scheduler

In manila/api/openstack/rest_api_version_history.rst,
underscores were used instead of hyphens to underline version '2.14'.
Fix to remove visual incongruity.

In doc/source/devref/scheduler.rst, not all drivers were added or
updated. Fix to include all drivers.

Partially-implements bp improve-manila-developer-docs
