And also be liberal in what ansible-doc accepts as an empty

make bin/ansible error output consistent for shell module as for the command module when no arguments

Decided to not deprecate legacy template syntax for now.  Backwards compat is important, though the docs will suggest the new way.

Add code to flag legacy templating like $foo.{bar} as deprecated in favor of Jinja2 {{ foo.bar }} so we
can remove the legacy system at a later date.

Change the retry logic to write a limit file, able to source limit from files by indicating with @filename

When playbooks fail, attempt to create an inventory file in the inventory directory that allows rerunning
of the playbook against only the hosts that failed.

Probably output is not useful if not used with --limit

Works well with --check mode

This implements a basic --check mode which for now is only implemented on template & copy operations.  More detail will be shared with the list
shortly.

This makes --list-hosts work more like actually running the playbook,
and thus gets the correct hosts with regard to includes and similar.

Fixes #1959.

add error handling when no arg passed to command module

check path is directory
added manpage & setup
small cleanup
shut up module_formatter in utils to avoid trace print on crud files in library

This reduces the amount of times an inventory script has to be invoked.

Currently when more than one playbook is provided on the commandline, ansible-playbook --list-hosts will only consider the first playbook and stop. This change will make it work for the various different playbooks.

When the inventory is empty, or the provided --limit subset returns an empty intersection, we don't want to loop over all plays but bail out at the very start.

refers to #1345

--limit takes localhost, FQDN, and 127.0.0.1.
