* 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 Co-authored-by: Aaron Clawson <MadVikingGod@users.noreply.github.com>
