Fix delete procedure for volume resource. Upon deletion, the volume
(PVC) does not produce a usable event. Thus watching the K8s resource
for state change will never yeild the expected result. As a consequence
the Terraform provider will eventually time-out and produce an error.
The fix is to watch for a resource state change instead of an event.
This will propagate the deletion of the resource appropriately and the
Terraform provider will succeed with the deletion.

Fix VM Network and Storage Class tests

Add negative test cases for IPPool and LoadBalancer resources. This
ensures that if mandatory parameters are not given, the program exits
with an appropriate error.

Add acceptance tests for VirtualMachine labels (tags) and LoadBalancer
resources. The labeling/tagging mechnism is crucial for these tests to
work, since a LoadBalancer is required by the admission webhook to have
at least one VM that matches its selectors.

Also improve documentation.
