Look for a file with the base name of the group/host, first without
a file extension, then with a '.yml' extension, and, finally, with
a '.yaml' extension, loading vars from only the first one found.
As documented in #2623, early variable substitution causes when_
tests to fail and possibly other side effects.
I can see the reason for this early substitution, likely introduced
in 1dfe60a6, to allow many playbook parameters to be templated.
This is a valid goal, but the recursive nature of the utils.template
function means that it goes too far.
At this point removing tasks from the list of parameters to be
substituted seems sufficient to make my tests pass. It may be the
case that other parameters should be excluded, but I suspect not.
Adding a test case. I would prefer to analyse not just the aggregate
statistics but also whether the results are as expected - I can't
see an easy way to do that with the available callbacks at present.
Technically this isn't quite valid YAML when this happens, so we make it valid. This means that if a future commander
API allows save/load it should make sure it does similar processing.
evaluate and replace '$item' with ''. Really it doesn't make sense to include multiple playbooks
via a loop variable, as you can do this with task + with_items already (and it's a simpler code
path). Given this is undocumented, this removes that feature, and we'll consider next how to
also add 'with_items' support directly to roles.
When operating on a unicode string in python 2.6, shlex.split returns
a result that does not work with the file constructor.
To reproduce this requires a task include that is templated (this is
because the templated string is a unicode result, whereas a non-
templated string is a non-unicode string)

The proposed fix (coercing the include parameters to string before the
shlex.split) may not be ideal but it does fix the bug for my test case.
