  Race between imagebackend and imagecache

Bug description:
  After ImageCacheManager judges a base image is not used recently and
  marks it as to be removed, there is some time before the image is
  actually removed. So if an instance using the image is launched during
  the time, the image will be removed unfortunately.

libvirt: Race condition leads to instance in error

ImageCacheManager deletes base image while image backend is copying
image to the instance path leading instance to go in the error state.

Acquired lock before removing image from cache. If libvirt is copying
image to the instance path, image cache manager won't be able to remove
it until libvirt finishes copying image completely.
