create task manager for async commands

[Toure]

This would give the user the ability to launch commands, placed into the background, and trigger on
event keyword.

example:

import asyncio

async def worker(cmd):
print("Doing something important")
doing_something_important(cmd)
return_prompt()

event = asyncio.get_event_loop()
event.run_until_complete(worker())

This would allow us to spawn jobs in the background and return a status info once the job has completed. Which in turn would allow users to start multiple jobs on the command line and not have to worry about checking status later as it can be dumped to a file or to the current session.
