MongoDB will exit in 7node example

[Antilochus]

When I try to connect Epirus to Quorum 7 Node Example, MongoDB will always exit.

It seems that '--smallfiles' has been removed since mongo v4.2. So I think if you use mongo:latest, this command-line option should be also removed in docker-compose.yml file.

@Antilochus good spot, I will submit a PR.
