Added method to return OpenStackVmInstance from Heat.

OpenStackHeatStack now can introspect the VMs that the template
was responsible for deploying and return an instanitated instance
of OpenStackVmInstance for each VM deployed. When the VM has a
Floating IP, these instances have the ability to connect via
SSH just like one created from scratch.
