[JENKINS-21671] Summarize Stapler bound objects

Find some way to obtain all the BoundObjectTable.Table instances held in session attributes, and produce a histogram of the implementation classes of the targets (referents). This can help diagnose potential memory leaks (JENKINS-16341">JENKINS-16341).

Raw content of original issue

Find some way to obtain all the BoundObjectTable.Table instances held in session attributes, and produce a histogram of the implementation classes of the targets (referents). This can help diagnose potential memory leaks (JENKINS-16341).

• environment: originally RM-1866

Start by locating BoundObjectTable.Table and the session-attribute handling in the support-core-plugin code. Determine how all held tables and their referent implementation classes can be identified; done means exposing a histogram that helps diagnose potential memory leaks, with behavior verified by the project's relevant tests if available.
