Enforce pubsub option required/rejected attributes

XEP-0060 states that 'node' and 'jid' attributes to <options> element MUST NOT
be included when <options> are specified at same time as <subscribe> :

https://xmpp.org/extensions/xep-0060.html#subscriber-configure-subandconfig

mod_pubsub will require 'node' and 'jid' attributes on standalone pubsub
options requests, and reject subscribe requests that have options that include
either 'node' or 'jid'
