(#9241) Add ability to find VMs by UUID

This patch adds two request methods to the compute service for VMware.
First, finding a VM by it's own UUID (from the vmx file) is supported.
This UUID is not guaranteed to be unique so this patch also implements
finding by instance UUID which is guaranteed to be unique.

The server models will primarily use these requests to obtain VM
managed objects to issue commands against.
