Very first implementation of incoming http tracking (#47)
* very first implementation of http in monitoring without any tests yet * WIP test project. It will break build * http in tests are now running OK. Time to start implementing an actual test * implemented http in test case * sharing files between collectors * update build to use 2.1.4 instead * removed copy/paste error * do not test testapp as a unit test * revert back 2.1 change * 2.1 yet again
