Bugfix/local docker performance

What does this MR do?

It increases the local performance of the foodsharing app in dev mode dramatically. Not sure if this will have any positive effect on Linux machines but for macOS this is a dramatically speed boost.

I was talking with @jofranz about the bad performance and after researching a bit I found out that adding :cached to the volumes may increase the performance. I also disabled volumes for less interesting services.

How confident are you it won't break things if deployed?
