MT#60476 origin-replace: introduce full and limited replace

Two version of the origin replace exist from now on:
- `origin-replace` - replaces only the origin address
- `origin-replace-full` - replaces all the values,
  so name, id, version and IP family with address.

Values for replacing are taken from the rtpengine instance,
so local values provided by the daemon.

Additionally: documentation updated accordingly.

Additionally: revert changes in pub-sub test.
