### What problem does this PR solve?
when do sample, it will use table.getRowCount() as rowsCount, but the
table.getRowCount() may be stale because it depend on BE's report, then it may
occur rowsCount < ndv.
Then when if 10 * rowsCount < ndv， the analyze sql will fail.
Then the regression test statistics/analyze_stats.groovy is not stable, and
cause error:
```
Exception:
java.sql.SQLException: errCode = 2, detailMessage = Failed to analyze
following columns:[id] Reasons: java.lang.RuntimeException: ColStatsData is
invalid, skip analyzing.

```
so when do sample and scan whole table, we use count(1) to represent
rowsCount.
Notice that this replace will not increase the excute cost, because the
staticstic sql has contained `count(1)`
