With cinder configured as glance store and nfs as cinder backend, if we create multiple images concurrently into the same share, there might be race conditions. This patch ensures a lock per export to avoid the race conditions. This patch also introduces a reference counting mechamism for unmounting which will unmount the share if no active thread/process is using it. Closes-Bug: #1870289 Change-Id: I9197f64e29a0ae2e0a58186f1a70aa134f7f1db6

Glance Store Library
Glance's stores library
This library has been extracted from the Glance source code for the specific use of the Glance and Glare projects.
The API it exposes is not stable, has some shortcomings, and is not a general purpose interface. We would eventually like to change this, but for now using this library outside of Glance or Glare will not be supported by the core team.
