Prepare for the 'Bare Metal' environment on vSphere

1. Copy the rhcos-X.X.X-x86_64-installer.x86_64.iso & Red Hat Enterprise Linux 8 iso to an ESXi datastore
2. Create a new Port Group called 'OCP' under Networking
3. Create 3 Control Plane virtual machines with minimum settings:
   • Name: ocp-cp-# (Example ocp-cp-1)
   • 8vcpu
   • 32GB RAM
   • 120GB HDD

• NIC connected to the OCP network

# TODO move these to config files

  "start_kind": True,
