Merge pull request #2646 from sevein/git-shallow-clone

Add support for shallow clones in the git module
This is a fix on top of the 'airplane variable upgrade' commits that fixes legacy when_string so it evaluates correctly in the new eval construct.
Prevent premature substitution of variables into tasks

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.
Quick fix for first_available_file and roles
Update pause module to not use utils.template
Remove unneeded import.
Avoid running through the legacy template code if no dollar signs are in strings.
