mod_admin_shell: Add debug:ping() which prints debug logs until pong Essentially a verbose version of xmpp:ping(), but more useful for debugging s2s issues without having to watch (and have enabled) debug logs at the same time and try to pick out where the start and end are.

module:log("error", "mod_pep_plus has been renamed to mod_pep, please update your config file. Auto-loading mod_pep...");
module:depends("pep");
