vagrant: Use a Fedora 29 container

Switch the Docker + Vagrant development docs to use a Fedora 29
build container, and a Fedora 29 Atomic Host Vagrant box. CentOS
7-based testing was recently removed (#1785) - let's have the
documented development pattern reflect this.

Also no longer enables the EPEL7 repo in the Vagrant VM, as needed
dependencies are available in Fedora Atomic Host.

A note is left to later switch to Fedora CoreOS as the documented
Vagrant box to use, once Fedora CoreOS boxes are produced.
Alternatively, one may use [cosa](https://github.com/coreos/coreos-assembler).

A few notes are also added to vagrant/README.md in places where
the reader may hit problems.
