Jose Diaz-Gonzalez a36256dbd9 docs: document the possibility of zombie processes on ssh disconnect for :connect and :enter commands
Apparently terminating the ssh connection that runs 'docker exec' may result in a process leak as the signal isn't propagated properly (moby/moby#9098). Since we cannot fix this, we should document it so that users do not stumble upon the issue unawares.

Closes dokku/dokku-postgres#212
