@Yun-Ting would you put a comment here explaining why min is 3? (consider updating the XML doc to call out the accepted range)

Yeah, one for the overflowAttribute when emitOverflowAttribute is set to true, and the other for 0 tag, assuming when users set this value, they want to pass in tags.
Currently, the lower limit for .SetMaxMetricPointsPerMetricStream() is 1, though.
In AggregatorStore, we reserved one for the overflowAttribute.
And in doc, it says one should be reserved for 0 tag (no key/value pair associated).
Also, there had been discussions on whether we should reserve 1 for zero dimension: #2635 (comment).
Maybe this topic indeed worth another PR.

LGTM. The current test cases are using reflection, I think eventually we should remove reflection and test against the real limits (e.g. set a limit and see if we hit it or not). Not blocking this PR since it requires many changes in other places (including fixing some bugs).
