* handle Python 3.5 (2nd try)
* go Ansible 2.3
* clarity++
* For realz this time
* Fix tempfile.mkstemp (#2)
* back to square one, removing temp file from the mix
* Adding temp back
* Adding tuple back
* Adding another tuple back
* Trying to get around weird Jenkins behavior of blowing up when both .hpi and jpi file found
* Incorporating PR feedback
* Delete .hpi file instead of backing it up, some basic clean up
* Moving file deletion to the right location
* Blank lines. They always get me.
* Allow re-using an existing template when updating a stack by not passing 'template' or 'template_url'. This is a big one for me as our deploy process creates a new stack and then modifies the old one; to avoid changing the resources inside the old one, we have had to avoid using the Ansible module and use the AWS CLI instead in order to pass `--use-previous-template`.
* Split create and update logic into separate functions
* Remove dead `update` variable
