This massive commit refactors all of the request methods on the
Fog::Compute[:vsphere] instance to return simple hashes. The behavior
before this commit returned full vmware object references which was a
problem because it was difficult to unit test.
With this patch, it is much easier to add and maintain Mock
implementations of the request methods. This makes adding behavior
tests for the server model much easier.
In addition, test coverage using Shindo has been added. Previously
there was little test coverage of the behavior.
To run the tests:
shindont tests/vsphere/
Without this patch we have no way to completely destroy
a server instance. This patch adds a vm_destroy API request
and implements the destroy method on the server model.
The vSphere API requires the server to be in a poweredOff state.
The model action and the request do not verify this is the case
before issuing the command.
