add osmo_verify_transcript_{vty,ctrl}.py for easier vty and ctrl testing

While adding VTY and CTRL tests to new programs like OsmoHLR, I wanted to have
a simple way to translate a VTY interaction transcript to a VTY python test. It
is fairly trivial to simply read in a transcript, extract both the commands to
send as well as the expected results, and to verify these without having to
write one line of application-specific code. From there it was just a little
step to allow the same for CTRL interaction.

With osmo_verify_transcript_vty.py and osmo_verify_transcript_ctrl.py, it is
possible to have a simple text file of a telnet VTY or CTRL interface
interaction and run it against a given application. With the --update option,
the scripts run the given command and rewrite the transcript file to whatever
the application currently produces as response. Backed by version control, it
is super easy to tweak commands, --update the test results and verify that only
the desired bits changed. A '...' wildcard can skip any number of lines in the
expected result and is usually preserved during --update.

This python3 implementation is independent from the previous obscvty
implementations.

Take the opportunity to clarify/fix a few aspects: for example, it is now
possible to verify the hints that the interactive VTY displays when the user
enters '?' in various places, and to evaluate the prompt character '>'/'#'.

Unitl now, code is duplicated/scattered across various vty_test_runner.py
scripts in different git repositories. Now, a VTY or CTRL transcript is enough
to put a complete test in place.

The simplest invocation is directly from the Makefile, feeding an application
commandline, the proper port number to contact it and e.g. a VTY prompt name.
This new code is also usable as python modules, to be able to build more
complex tests that require specialized intermediate actions, possibly
coordinating launch of applications or data manipulation.

The first repository to employ this is osmo-hlr.git. See change-ids
I42b3b70a0439a8f2e4964d7cc31e593c1f0d7537 for VTY and
Iff93abe370b8f3ecf42082d1d0eaa1fbeca5b122 for CTRL.
