[refactor] separate url mapper, avoid hanging tests

Because the wsgi resource has its own threadpool, tests might get
confused when shutting down and the reactor may get clogged waiting for
the threadpool to be stopped. By refactoring the URLMapper to its own
module, server tests can avoid loading the resource module, where the
wsgi threadpool resides, so the threapool will not be started.
