Update to mongo 4.0

[Ameausoone]

Update MongoDB version to 3.4 Use docker volumes instead of local storage Use default standard MongoDB ports Use wait-for-it.sh to wait until Mongo servers are available (but there is better way to wait until servers are fully ready) Add Makefile Update documentation
