<br>
For greater flexibility, the option should not be a module param, instead a flag for save, so the two options can be used simultaneously.<br>
Also, all the functions provided by the ims_registrar_scscf should have the "scscf_" prefix, just like the ims_registrar_pcscf module to avoid overlapping with the generic registrar module.<br>

>> Running our testcase on a version previous your commit, the 200OK of the second registration lists 2 bindings (correctly, as we expect by the RFC).
