prosodyctl: Add external connectivity check based on observe.jabber.network This uses the (experimental) observe.jabber.network API to perform external connectivity checks. The idea is to complement the checks prosodyctl can already do with a (nearly) complete s2s/c2s handshake from a remote party to test the entire stack.
