------------------------------------

It is possible to reuse Exec and ExecResult. Just ignore / don't set the row
fields etc. Having separate classes for master exec only is not a clean API in
my opinion.

Apart from being a bit clunky I made them separate so that each class can
evolve without master/region usages stepping/confusing on each other. If you
think this is ok I'm fine with reusing the Exec and ExecResult.
