google-cloud-storage v1.8.0

Not sure whether rewrites are supposed to work when batched, but it would be nice and useful if they did, otherwise there's no efficient way to copy lots of blobs across buckets in different locations or with different encryption keys.

Example:

with gcs_client.batch():
    dest_blob.rewrite(src_blob)

Traceback:

Traceback (most recent call last):
  File "batch_test.py", line 10, in <module>
    dest_blob.rewrite(src_blob)
  File ".../pyvirtenv/python-common/lib/python2.7/site-packages/google/cloud/storage/blob.py", line 1359, in rewrite
    rewritten = int(api_response['totalBytesRewritten'])
  File ".../pyvirtenv/python-common/lib/python2.7/site-packages/google/cloud/storage/batch.py", line 105, in __getitem__
    raise KeyError('Cannot get item %r from a future' % (key,))
KeyError: "Cannot get item 'totalBytesRewritten' from a future"
