vty expect script

[Neels Hofmeyr]

Hi Keith,

I'm now using your vty expect script from
https://gerrit.osmocom.org/#/c/osmo-dev/+/11811/ in our congress gsmcore setup,
and I absolutely love it!

I tweaked the logging, and next to it I also put vty_sticky, which re-opens the
vty when the program gets restarted. Attached my current versions.

Such a simple and nice way to customize logging, easily attach and detach,
quickly change some log levels... much simpler than navigating journalctl.

Thanks for that!
