Install Vault using RPM repository instead of Docker
In accordance with the Hashicorp Vault Production Hardening recommendations:
Single Tenancy. Vault should be the only main process running on a machine. This reduces the risk that another process running on the same machine is compromised and can interact with Vault. Similarly, running on bare metal should be preferred to a VM, and running in a VM should be preferred to running in a container.

Note that this also moves from Vagrant/Virtualbox driver to Docker driver for the Molecule tests.
