Description

When CombineSelectionPolicy is used as a selection policy class with ConfigBasedDatasetFinder, there is no constructor with appropriate signature for instantiation from ReplicationValidPathPicker class and we get an exception like the following:

java.lang.IllegalArgumentException: java.lang.NoSuchMethodException: No such accessible constructor on object: org.apache.gobblin.data.management.policy.CombineSelectionPolicy

We need to provide a constructor for CombineSelectionPolicy with only the selection config as an argument.
