Remove driver-specific notes from extend api-ref
This is not part of the API contract.  It should
be documented elsewhere as a limitation of the
volume driver.

- .. note:: Some volume backends require the storage to be in some multiple
- value rather than incremental. For example, the EMC ScaleIO backend
- requires storage in multiples of 8GB. There is a known limitation such
- that a request to extend the size of a volume for these backends will be
- rounded up to the nearest multiple but the actual physical size of the
- storage will not be reflected back in the API for the volume size. For
- example, a request to extend the size of an 8GB ScaleIO-backed volume
- to 9GB will actually result in 16GB of physical storage but only 9GB will
- be reflected in the API and counted for quota usage.
