aws.s3_{down,up}load_file not working

[jjacque]

Hi, i've an issue with those 2 functions , it seems the way boto3.client is called is an issue:

st2 run aws.s3_download_file filename="/tmp/toto12345" bucket="test-bucket" key="st2-test-1"
.
id: 5bd8376c2239205175d29e9d
status: failed
parameters:
  bucket: test-bucket
  filename: /tmp/toto12345
  key: st2-test-1
result:
  exit_code: 1
  result: None
  stderr: "st2.actions.python.ActionManager: DEBUG    Calling method "boto3.s3.transfer.S3Transfer.download_file" with kwargs: {u'headers': None, u'bucket': u'test-bucket', u'key': u'st2-test-1', u'filename': u'/tmp/toto12345'}

I managed to get it work with the following changes #71 Not sure that's the best way but it fixes the issue leaving parameters unchanged.

st2 --version
st2 2.9.1, on Python 2.7.12

Resolved with #71
