net.http: fail open if surrounding code does not configure TLS Previously, if surrounding code was not configuring the TLS context used default in net.http, it would not validate certificates at all. This is not a security issue with prosody, because prosody updates the context with `verify = "peer"` as well as paths to CA certificates in util.startup.init_http_client. Nevertheless... Let's not leave this pitfall out there in the open.
