[jira] [Created] (BEAM-767) Add DisplayData builder '.nested(..)' operation

Scott Wegner created BEAM-767:
---------------------------------

             Summary: Add DisplayData builder '.nested(..)' operation
                 Key: BEAM-767
                 URL: https://issues.apache.org/jira/browse/BEAM-767
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Scott Wegner
            Assignee: Scott Wegner


See: https://github.com/apache/incubator-beam/pull/1088#discussion_r83332515

In the Java SDK, components can register display data directly, as well as include display data from sub-components via the 'include(..)' operation. In [BEAM-1008|https://github.com/apache/incubator-beam/pull/1088], we add 'paths' to display data metadata and also include a 'delegate(..)' action.

During the change for paths, we noticed an emerging pattern where components will typically add the .getClass() of a subcomponent before including it. We can support this convention better by embedding it in a single configurable operation, '.nested(..)'
