* Split calls to finding hardware keys into sync and async methods. This has the side effect of simplifying the code. * Check for keys before performing challenge/response if no keys have been found previously. * Correct timeout of user interaction message to interact with the hardware key. * Correct error in TestCli::testYubiKeyOption
