Add functions for retrieving multiple artifacts

Add functions for retrieving multiple artifacts

Add the functions AbstractComponentFunction
.storedArtifactNamesAndResolutionKeysNB()
to retrieve all artifact_names and resolution_keys for a given
blueprint and AbstractComponentFunction
.storedResolutionKeysForArtifactNameNB(artifactName)
to retrieve all resolution_keys for a given blueprint and artifact_name.
To support the required JPA query, an interface
TemplateResolutionSelector was added in resource-resolution.
