Adapt vagrant network setup to dhcp

[hennevogel]

This should work for everybody and not conflict with random ip ranges. @kirushik what do you think?

It would be great to have this, but then we need a better way of adding Vagrant host to the better_errors middleware.
I was unable to figure out anything better than hardcode: https://leprosorium.ru/comments/1867892/#new

I also have new problems with the network & directory sharing. The vagrant network situation seems pretty shaky...

Rebuilding the VM did the trick

Yes, unfortunately that's also the issue for me recently.
I don't know if that's VirtualBox bug, or the image itself. vagrant up won't work after vagrant halt, can only be solved with vagrant destroy.

I'd like to change our virtualbox base image to eliminate the most obvious reason for such a bug, but there are no other 13.2-based images at the moment: https://atlas.hashicorp.com/boxes/search?utf8=%E2%9C%93&sort=&provider=&q=opensuse

vagrant reload helps me sometimes...
