Add Validation Support for Process Plugins

[jaboehri]

Related Problem

Process Plugins may require validation support for testing purposes. Existing classes that supported this were available as artifacts in DSF 1.x: ResourceValidatior, ResourceValidatorImpl and ValidationSupportRule. They are not available as artifacts for DSF 2.x yet.

Describe the Solution You’d Like

Make classes like ResourceValidatior, ResourceValidatorImpl and ValidationSupportRule available as a new module e.g. dsf-bpe-process-api-v2-test-support.

Describe Alternatives You’ve Considered

Alternatively, publish them as a test-jar of dsf-bpe-process-api-v2.

The classes and base FHIR resources needed for executing tests of process plugin FHIR profiles are located in the dsf-fhir-validation module. We should publish the module so that process plugins developers using API v2 can use it as a test dependency.
