  aaa_diameter: Fix acc_extra / acc_leg accounting

This commit adds support for dynamically configured AVPs in both
OpenSIPS (client-side) and freeDiameter (server-side), such that they
can be added to the sent message and parsed from the received message.

The syntax is identical to the RADIUS configuration file, e.g.:

    ATTRIBUTE out_gw     231 string
    ATTRIBUTE trunk_id   232 string
    ...

(cherry picked from commit ba7077ade98570c1ad61618ae9130b77893d64bd)
