[raster] Report _add_raster_constraint violation error details
|Reported by:||mloskot||Owned by:||Bborie Park|
Currently, _add_raster_constraint functiond does not report any details about the reason of skipped constraint. It makes it difficult to diagnose constraint problems.
For example, without replacing the blocksize constraint conditions (see patch for #2122), the blocksize constraint is silently skipped with no detailed reason provided.
