A filter to schedule instances on hosts containing specific volumes.

Registered by Alexey Ovchinnikov on 2013-05-17

To reduce latency it may be desired to place instances physically close to volumes associated with them. To achieve this we may try scheduling them on hosts, containig those volumes. An obvious way to do this is to use scheduling mechanism already present in nova. Nova scheduler can be extended with extra filter allowing to choose a host to which specified volumes belong.
