PlayContext.delegate_to is the unexpanded template, Ansible doesn't keep
a copy of it around anywhere convenient. We either need to re-expand it
or take the expanded version that was stored on the Task, which is what
is done here.
Unclear whether or not this is a hack, or whether it should be the
default for more connection methods. When enabled, the exception text
thrown when bootstrap fails includes the stderr text, which is
apparently always useful.
This needs more work -- pretty certain that python_path and suchlike are
coming from the wrong place. Possibly we need another config_from_..()
specialized for delegate_to.
This change is relatively incomplete -- ideally we could snapshot
os.environ and /etc/environment at startup and respect key deletions
too, but that's a lot more work. Wait for a bug report instead.
Closes#338.
Concurrent calls to ModuleDepService would cause significant wasted
work, as potentially all pool threads run the same uncached module dep
scan.

Ignore timing variance due to problems with the test job.
Given an extracted download of mitogen-2.2.tar.gz, with strategy_plugins
pointing into it, if an old version of the package was pip-installed,
then the old pip-installed package would be imported and override
whatever came from the tarball.
Instead, modify sys.path before attempting any import. This still isn't
perfect, but it's better.
