Update both ReAuthorize API signatures

The one from sessions takes an additional event alongside the
SessionFilter, while the one from agents will accept a CGREvent
instead of a simple originID string

The additional event sent to SessionSv1ReAuthorize will be merged
with the EventStart event from the matched session and can be used
when building server initiated requests from the *req map. The
initial packet which was initially inside *req, will be moved to
the *oreq ExtraDP (stands for original request).
