fix: don't delete runtime dir on process down

[sandydoo]

Fixes #1270.

@domenkozar, should we be deleting the runtime dir when taking down processes? Any good reason to do this?

There are a few issues with this line:

1. It relies on trapping a signal. In the case of process-compose, I think the reason it's immune from this failure is because the trap is never triggered. We need to rethink how we run post-process actions.
2. We create the runtime dir in the CLI, but try to delete it in the shell script. This sounds like a bug magnet to me.
3. There was an issue a while back where redis would crash on shutdown because of a race condition here.

Maybe instead we should delete it on startup? To start fresh?
