Dmitry Lychagin updated ASTERIXDB-2434:
---------------------------------------
Description:
Computation of required child properties for some operators (UnionAll, for
example) depends on the execution mode of its children
(OperatorPropertiesUtil.checkUnpartitionedAndGetPropertiesVector()). Therefore
it's important to have correct execution mode for all operators at that time.

We invoke SetExecutionModeRule during logical rewrites, but by the time
EnforceStructuralPropertiesRule is invoked there might be new operators in the
plan. We need to invoke SetExecutionModeRule right before
EnforceStructuralPropertiesRule to guarantee that execution mode is properly
set for all operators.
