res_pjsip_outbound_registration: registration stops due to fatal 4xx response
During outbound registration it is possible to receive a fatal (any permanent/
non-temporary 4xx, 5xx, 6xx) response from the registrar that is simply due
to a problem with the registrar itself. Upon receiving the failure response
Asterisk terminates outbound registration for the given endpoint.
This patch adds an option, 'fatal_retry_interval', that when set continues
outbound registration at the given interval up to 'max_retries' upon receiving
a fatal response.

+res_pjsip_outbound_registration
+-------------------------------
+* A new 'fatal_retry_interval' option has been added to outbound registration.
+ When set (default is zero), and upon receiving a failure response to an
+ outbound registration, registration is retried at the given interval up to
+ 'max_retries'.
