* Code formatting (indentation and white space) fixes for improved PEP8 conformity.
* Remove redundant backslashes inside parentheses.
* Test for object identity should be 'is not None'.
* Test for membership should be 'not in'.
* Fit docstring to the PEP8 79 character limit.
* Use forward compatible Python 2.6+ 'except .. as' syntax for exception handling.
* Support libcloud > 0.15 'metadata' argument format.
My project is using Ansible to automate cloud build process. Ansible has a core module gce.py for managing GCE instances.
We've come across a use case that's not yet supported - when executing ansible-playbook, if a child template is included, then metadata which is defined in and propagated from the mother template is treated as string type and not parsed correctly(which instead is dictionary type), and triggers release flow failure.
We currently put some fix by explicitly casting metadata to string type in our own branch, but would like to contribute the fix to Ansible so that everyone onboarding GCE and using Ansible for release management could benefit from it, or hear owner's opinion on fixing the issue if there's a better fix in owner's mind:)
* Fix docs to specify when python2.6+ is required (due to a library
dep). This helps us know when it is okay to use python2.6+ syntax in
the file.
* remove BabyJson returns. See #1211 This commit fixes all but the
openstack modules.
* Use if __name__ == '__main__' to only run the main part of the module
if the module is run as a program. This allows for the potential to
unittest the code later.
