Previously we were using ping or just an ssh connection to validate a

deployed VM. Now we are verifying that the agent id matches the deployed
VM by comparing the agent id returned from a 'bosh vms --details'
command along with the 'hostname' of the deployed VM (which should be
the agend id). Additionally, another concern of the previous approach
was that it used ping when the port isn't guaranteed to be open, unlike
SSH.
