Description
Add feature control flag to control random scans used by INFER, ADVISE & UPDATE STATISTICS (0x40000/262144).
INFER's use of random scans is also controlled by the existing sequential scan flag (0x4000/16384) since the sample size can be specified to effectively run a sequential scan on larger collections. It also separates largely user-driven activity from implicit activity for more control options.
