    @paul-rogers Thanks for the explanation. Your explanation is in sync with Arina's descriptions
in the ticket and with the code changes. The only point of confusion I have now is with regards
to the Calcite things changes you mentioned. I was under the impression that the following
happened:
    
      1. FormatPlugins created a DrillTable, which held the format configuration. 
      1. The DrillTable is then encapsulated in a ScanOperator
      1. The ScanOperator automagically gets serialized into the PhysicalPlan with the DrillTable
and corresponding format configuration correctly.
    
    But it seems like there are more Calcite things at work here. @arina-ielchiieva could
you please point me to the general flow I need to look at in order to understand how the FormatPluginConfig
interacts with Calcite and gets serialized into the PhysicalPlan?
