KUDU-3518: Fix the unexpected scan predicate
With the changes introduced in a previous patch[1], there have been
reports of errors during scan operations. This patch fixes these
scan errors.
This patch removes NON-NULL predicates on primary columns implicitly
added by ScanSpec::LiftPrimaryKeyBounds(), calling
ScanSpec::OptimizeScan() while optimizing InList scan predicates at the
DRS level. That's similar to what's done be optimizing the InList
predicates based on tablet PK bounds at a higher level.
The issue has been investigated and fixed in collaboration with Alexey
Serbin.
There will be follow-up patches to include tests of this failure.
