[API EPIC 4/4] Fix tests and examples (#2587)
* Empty All of the metrics dir

* Add instrument api with documentation

* Add a NoOp implementation.

* Updated to the new config standard

* Address PR comments

* This change moves components to sdk/metrics

The Moved components are:
- metric/metrictest
- metric/number
- metric/internal/registry
- metric/sdkapi

* The SDK changes necessary to satasify the new api

* This fixes the remaing tests.

* Update changelog

* refactor the Noop meter and instruments into one package.

* Renamed pkg.Instruments to pkg.InstrumentProvider
