* Rename *Provider names
There is overlap in naming with MeterProviders and TracerProviders. This
is means the specification is not implemented and these types can not
exist in the same package (#1179). This makes each type and related
functions and types explicit.
* Add changes to CHANGELOG
* Unexport NoopXXX trace types
The change unexports the noop implementations and provide the NoopProvider function for user to construct noop providers. Users can access noop tracer and noop spans by using the provider.
This change removes the types users should never be directly using from the package. It improves the usability of the API by reducing the API surface to half and helping the user to focus on the canonical APIs.
Fixes#1133
* Provide noop tracer and span for internal use
* Remove obsolete doc
* Use noop span instead of nil
* Fix the broken build
