This Reservoir implementaiton is used at the MeterProvider level to
pre-filter measurements offered to a wrapped Reservoir.
Co-authored-by: Robert Pająk <pellared@hotmail.com>
* Add the sdk/metric/internal/exemplar pkg
* Rename testReservoir to ReservoirTest
This is a test helper function that is not exported outside of testing
for the package. Use the exported name so the CI system doesn't complain
about it not being used. It will be used in follow-up PRs.
* Run go mod tidy
* Update versions.yaml
Move experimental-metrics modules that are stbilizing to the stable-v1
module-set.
* Prepare stable-v1 for version v1.23.0-rc.1
* Update changelog

* 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
