terminal dashboard: should be very similar to web dashboard in appearance, allow for "monitoring"

I remember me mentioning https://github.com/pyout/pyout/ and you looking at it, but I do not see any mentioning of it here, so decided to make an issue.

Currently there is a web dashboard, but terminal representation qme ls is a printout of current status (which is good) but has no ability to become persistent/updating -- i.e. I just run it in a terminal and see it updating from time to time with status of completed jobs etc, like I hope web ui would do too at some point (ATM I do not see any "status" column).

Also with pyout it might be easier to make terminal printout also better "structured", e.g. to include the header to

1  shell-effb7576-f0da-431f-8e5a-16419753b9aa	bash -c date; sleep 10; date
2  shell-c42c2e0b-ac91-4efd-bc78-4093a9c0c1db	bash -c date; sleep 60; date
3  shell-00d909b6-2119-4e97-8669-449f6786c8bd	bash -c date; sleep 2; date

so it looks more like what is shown in web dashboard:

Id | Executor | Name | Command
-- | -- | -- | --
2 | shell | Shell-00d909b6-2119-4e97-8669-449f6786c8bd | bash -c date; sleep 2; date |  
1 | shell | Shell-c42c2e0b-ac91-4efd-bc78-4093a9c0c1db | bash -c date; sleep 60; date |  
0 | shell | Shell-effb7576-f0da-431f-8e5a-16419753b9aa | bash -c date; sleep 10; date

NB wow -- how the heck cut/pasted table from web ui comes as a markdown?! awesome
