#### Description

LCR module exports information about selected gateways in flags and tag AVPs if you define corresponding modparams (flags_avp and tag_avp).

This PR exports a similar optional AVP that stores the id of the rule that selected each gateway. For that, a new modparam is added (rule_id_avp).
