[SPARK-17515] CollectLimit.execute() should perform per-partition limits ## What changes were proposed in this pull request? CollectLimit.execute() incorrectly omits per-partition limits, leading to performance regressions in case this case is hit (which should not happen in normal operation, but can occur in some cases (see #15068 for one example). ## How was this patch tested? Regression test in SQLQuerySuite that asserts the number of records scanned from the input RDD.
