mod_delegation: use clean_xmlns to remove jabber:client namespace from node: for the same reason as in mod_privilege, `jabber:client` namespace is removed with the clean_xmlns method coming from there. Furthermore, the forwarded <iq> stanza use the `jabber:client` xmlns while the stanza may come from a component with e.g. `jabber:component:accept` xmlns, this can lead to inconsistencies between the <iq> stanza and children (like <error> element).

This module advertises STUN/TURN service to clients via XEP-0215 (it utilizes
mod_external_services to do so, which will be automatically loaded by this
module and must be available).

This module is included with Prosody 0.12 but made available here for older
versions.

Documentation is available on the [Prosody site][doc:modules:mod_turn_external].
