(#9241) Add test skeleton framework

Without this patch the change set currently has no framework for testing
the Vsphere provider.  This patch doesn't actually test anything, but
does add the skeleton code to being testing mocked versions of other
code.

Particularly, we're going to take the approach of completely mocking the
@connection instance variable of the Compute instance.  This will allow
us to set expectations and return things from the underlying vmware API
library.
