* Fixing error exception handling for python. Does not need to be compatible with Python2.4 b/c boto is Python 2.6 and above.

* Fixing compile time errors IRT error exception handling for Python 3.5.
This does not need to be compatible with Python2.4 b/c Boto is Python 2.6 and above.
This is to address this error:
fatal: [site]: FAILED! => {"changed": false, "failed": true, "msg": "Failed to connect to S3: Region does not seem to be available for awsmodule boto.s3. If the region definitely exists, you may need to upgrade boto or extend with endpoints_path"}
Commit 0dd58e9 changed the logic so an exception is thrown (by
`connect_to_aws`) before the `s3 is None` check is performed. This
changes the `None` check to a catch so the old logic can compensate.
boto can throw SSLError when timeouts occur (among other SSL errors). Catch these so proper JSON can be returned, and also add the ability to retry the operation.
There's an open issue in boto for this: https://github.com/boto/boto/issues/2409
Here's a sample stacktrace that inspired me to work on this. I'm on 1.7, but there's no meaningful differences in the 1.8 release that would affect this. I've added line breaks to the trace for readability.
