misc: add a script for vm test env

Vagrant will not always be available everywhere, sometimes we want to
bootstrap a ceph on a virtual machine. This script will help you
bootstrapping a ceph cluster from a development branch only.

So you can run it like this: ./ceph-aio-no-vagrant.sh v10.1.0
To get the v10.1.0 version installed. If the first argument ($1) is
empty then master will be used in consequence.
