Add Option register_retry_403=yes/no

We had many problems with our trunk
Sometimes the providers send us this log

[2017-02-23 00:53:27] WARNING[3263] chan_sip.c: Forbidden - wrong password on authentication for REGISTER for 'XXXXXXXXXX' to 'sip.XXXXXXXXXX.at'
[2017-02-23 00:53:28] WARNING[3263] chan_sip.c: Forbidden - wrong password on authentication for REGISTER for 'XXXXXXXXXX' to 'sip.XXXXXXXXXX.at'

After that, asterisk does not make any retry to connect.
We had to restart the trunk manually.

Asterisk made a patch years ago for this problem:

Maybe you can include this Registration settings to your Framework?

Update.....
I tried the trunk now with the above setting in sip_custom.conf

Asterisk shows now some different logs and retries the connect until the trunk accepts the connection with the password:
