* Update Tracer API with instrumentation version Add option to the `Provider.Tracer` method to specify the instrumentation version. Update the global, noop, opentracing bridge, and default SDK implementations. This does not propagate the instrumentation library version to the exported span. That is left for a follow-on PR. * Revert trace_test.go This is for the next PR. * Update SDK to include version for default instrumentation If the instrumentation library name is empty and the default instrumentation is uses, include the SDK version. * Update comments and documentation * Remove default instrumentation version
