Container specific components

During the process of interpreting the workflow specified by the user, the conversion engine should findout which component shall be used according to the container because some components may be optimzed for some container.
For instance the spark engine has a Cassandra specific input reader implementation that we should leverage whereas we have our own implementation for DI.
So we should implement a way to group components which would have the same purpose but for different runtime container. Those components would mostly share the same properties but also have specific container properties.
