This runs the commands asynchronously (but waits for their
completion). This is more robust for long-running commands
because it avoids the built-in ssh timeout.
This adds an ansible module to actually run the remote command
so that we can:
* process the console log
* use ansible async (the script module does not support it)
* control the environment variables of the script being run
It also adds a callback plugin to track the elapsed time so that
we can use the built-in timeout features of async commands.
Note that the module and plugin are GPL licensed.
