Expose private IP for VMs

Allow the VM's private IP address to be accessed as a property.
Add option to skip ssh_endpoint

The current behaviour is to create an SSH endpoint on port 22 (if
available), or on a random port if it's not, for any new Linux VM.

This commit allows this endpoint creation to be skipped, which is
useful for machines on a virtual network, which don't require
public remote access.
