Tyler Yahn e3bf787c21 Add cardinality limiting to the metric SDK as an experimental feature (#4457) ... * Add agg limiting func * Add unit test for limitAttr * Add limiting to aggregate types * Add internal x pkg for experimental feature-flagging * Connect cardinality limit to metric SDK * Replace limitAttr fn with limiter type The Attribute method is still inlinable. * Use x.CardinalityLimit directly * Simplify limiter test * Add limiter benchmark * Document the AggregationLimit field * Test sum limits * Test limit for last value * Test histogram limit * Refactor expo hist test to use existing fixtures The tests for the exponential histogram create their own testing fixtures. There is nothing these new fixtures do that cannot already be done with the existing testing fixtures used by all the other aggregate functions. Unify the exponential histogram testing to use the existing fixtures. * Test the ExponentialHistogram limit * Fix lint * Add docs * Rename aggregation field to aggLimit --------- Co-authored-by: Robert Pająk <pellared@hotmail.com>		2023-12-19 07:53:01 -08:00
