Distinguish between stopped processes and processes that don't exist

[zmitchell]

Feature Request

Show a different error message when attempting to stop a process that is no longer running vs. attempting to stop a process that never existed in the config.

Use Case:

One of these indicates a user error (perhaps you made a typo entering the process name), and one of these indicates that a process may have terminated earlier than you expected. These are two different cases and a user may want to take different actions based on which error they encounter.

Proposed Change:

There's already an internal record of which processes exist because completed processes are shown in process-compose process list. You can use this record to disambiguate between these two cases.
