XD-1144 Update gradle build to pull in spring-data-grid snapshot

Also fix DeploymentTransformerTests.noopTransformation by adding
equals/hashcode to ModuleDeploymentRequest now that the transformer
is doing a deep copy.  It is quite likely that improved versions
of the DeploymentTransformer will not return the same data structure,
DeploymentModel - but instead something dedicated to model
the physical deployment.
