Since the YAML data format is a subset of JSON, it is trivial to convert
the former to the latter. This means that we can use YAML templates to
build cloudformation stacks, as long as we translate them before passing
them to the AWS API. I figure this could potentially be quite popular in
the Ansible world, since we already use so much YAML for our playbooks.
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.
