Common implementation of the GNUNET_TRANSPORT_TESTING_CheckCallback.

Starts and connects the two peers, then invokes the connect_continuation from cls. Sets up a timeout to abort the test, and a shutdown handler to clean up properly on exit.

Parameters
clsclosure of type struct GNUNET_TRANSPORT_TESTING_ConnectCheckContext
tth_initialized testing handle
test_plugin_name of the plugin
test_name_name of the test
num_peersnumber of entries in the cfg_file array
cfg_filesarray of names of configuration files for the peers
Returns
