Fix MacOS performance issues via docker-sync (MVP available)

First MVP for docker-sync available

Good guy chiribuc has just shared a Devilbox docker-sync example via GitHub Devilbox issues [1].


Please do try it out and report back how well it works for you.

Once I have gathered a very generic setup, this will be integrated into the Devilbox by default.
