Implements blueprint separate-nova-volumeapi

* Moves openstack/v2 directory to compute and fixes tests accordingly
 * Moves some code from api/openstack/compute to shared location, for use by volume api
 * Implements basic volume functionality for types, volumes, and snapshots
 * Changes service name from osapi to osapi_compute (and adds osapi_volume)
 * Renames nova-api-os to nova-api-os-compute, adds nove-api-os-volume
 * Separate extension mechanism for compute and volume
 ** Removes flag osapi_extension and replaces with osapi_compute_extension and osapi_volume_extension
 * Updates the paste config
 * Fixes setup.py to include nova-os-api-compute and nova-os-api-volume
 * Fix bug in volume version code that occurred as result of trunk merge
 * Update integrated/test_volumes.py to use new endpoint
