Introduce Asterisk_Tests testsuite

Add initial infrastructure to run tests against an Asterisk process.
An not-yet-finished draft test doing registration is submitted to
validate communication towards Asterisk works.

The testsuite will be improved in follow-up commits, but this way other
people can already start using it and we can set up the dockerized setup
+ jenkins jobs to run it nightly.
