vty_test_runner: update ipa sending code

Factor out 2, add 3 functions. Those functions are simple wrappers
around hex strings specific to IPA protocol. Not all of them are
utilized at the moment but they were checked with wireshark while
working on the tests. It might come in handy if we'd like to further
expand related test harness in future. The same goes for optional
verbosity argument which is not used right now but will be handy for
future debugging.
