Thanks for the PR. Changes are nicely done. One suggestion - Should we expose the config api in the SDK and not the API. As of now, the instrumentation library shouldn't be able to specify the metrics configuration, it should be done only by SDK (through View API?). There have been some discussions earlier to expose the config through API - Configuring histograms in the API (hints?), Add the metrics API Hint - but was not added to specs.

@lalitb thanks, removed from api.
