PRD-4129: Legacy mode. Dont use width for now (leave that for 5.0) and stick with min-width for the time being.
PRD-4317: In 'Select Datasource' dialog if user has query selected then disable delete action. Also cleaned up the datasource panel API.
Crosstab-sequence datasource was purely random, and thus was not suitable for golden sample tests.
Added random-seed to fix that.
Crosstab-Sequence needs random-seed parameter to make output predictable for golden-sample tests
PRD-4129: After migration we still have a min-width set.
