Add a testcontainers_wiremock#RunContainerAndStopOnCleanup() method…

… to simplify automatic termination (#30)

* testcontainter with auto termination

* testcontainter with auto termination

* id for WithMappingFile() function is paramparameterized

* fix for RunContainerAndStopOnCleanup

* using the updated RunContainerAndStopOnCleanup on quickstart_test.go
