class ViewsRevisionsConverter in Config Entity Revisions 8

Provides upcasting for a view entity to be used in the Views UI, with revisions support.

Example:

pattern: '/some/{view}/{revision_id}/and/{bar}' options: parameters: view: type: 'entity:view' tempstore: TRUE revision_id: \+d

The value for {view} will be converted to a view entity prepared for the Views UI and loaded from the views temp store, but it will not touch the value for {bar}.

This class extends AdminPathConfigEntityConverter rather than ViewUIConverter so that ViewUIConverter's converter can be replaced rather than extended (we call the parent method). Other methods should remain the same as ViewUIConverter.
