      Description

      1. Provide Convention.transformRelBuilder() to transform an existing RelBuilder into one with specific convention.
      2. RelBuilder provides withRelFactories() method to allow caller swap the underlying RelFactories and create a new builder.
      3. Use the new interface in RelCollationTraitDef for converting into RelCollation traits

      We can avoid ~1/3 of total rule firings in a N way join case with this change.
