Add --all flag to kill

Browse Source 
This allows a user to send a signal to all the processes in the
container within a single atomic action to avoid new processes being
forked off before the signal can be sent.

This is basically taking functionality that we already use being
`delete` and exposing it ok the `kill` command by adding a flag.
