* named tracer prototype * rename Manager to Provider. * fix compile error after merge. * rename Tracer method to GetTracer * provider with options. * update test. * cleanup make circl-ci * remove global config. * some cleanup. * use provider for bridge * update propagation test. * update examples and plugins. * remove GlobalTracer methods. * fix review comments. * some more cleanup. * remove unnecessary getTracer call in benchmark test.
