Interactive and progress reporting omnibus

Here is a list of features
* Turn on progress reporting for a running command (you hit enter 2 minutes ago, is it still going?)
* Show elapsed time on the heartbeat
* heartbeat should show number of operations running (if i start 4 vms with --progress, how many are left)
* In `--verbose` mode, output start and total time of the deployment
* Remove layout from F1 spot, and put Keys there instead, and call it help
* fix all the reflow issues (jpterm handles this WAY better)
* fix all the output errors (F3 makes the status bar move back and forth)
* add examples to `az interactive -h`
* we should cache outputs of `--progress` tasks and provide a `progress history` they can look at (create a vm with --progress, but get the IP address when it is done)
* add a message carasol to the bottom where the heartbeat goes.
