statistics: add sampling logger

[Rustin170506]

What problem does this PR solve?

Issue Number: ref #50132

Problem Summary:

If table analysis fails or there are no tables to analyze, we need to avoid printing duplicate logs.

What changed and how does it work?

We have added a sampling logger that prints only two same logs within a minute. However, please note that we cannot keep creating the logger repeatedly. It is necessary to keep it as a singleton so that we can track the same log counts with the same logger. Otherwise, the logger won't function as intended.
