    Cache snapshots in request for extension

    The extended snapshots extension makes a separate db request for
    snapshots which is horribly inefficent. In addition it causes an
    issue when using all_tenants=1, because the second request doesn't
    pass in the filter. Fix this by caching the snapshot in the request
    object like we do for volumes and retrieve the cached object in the
    extension.
