Deleting snapshots is very slow when the VersionStore contains many snapshots #837

For libraries with multiple snapshots, deletion can be quite slow as it involves serial listing and deletion. Will take a look if we can delete_many in mongo with a list of snapshot names. I do wonder about the atomicity of that operation.
