WIP: Named tracer prototype (#227)
* 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.
