This patch adds the ablity to set ssh port, and use key based
authentication for VPD.
This patch adds config options:
virtual_power_ssh_port: port to ssh to on virtual power host
virtual_power_host_key: private key file for ssh auth
Note: Key file must be able to be read by user nova is running as.
This patch switches the default virtual_power_type from 'vbox'
to 'virsh' to match the most common usage.
