register gateway using outbound-proxy and register-proxy, realm is resolved with dns timeout - missing repply to 401 Forbidden

[wmasilva]

Describe the bug
when creating a gateway using outbound-proxy and register-proxy parameters using IP address the realm is still resolved by sofia. If there is an issue with the DNS resolver the gateway will not register to the IP address configured on proxy parameters.

To Reproduce

1. Gateway parameters:

<gateway name="pruebaLinea">
<params>
<param name="context" value="incoming"/>
<param name="realm" value="lab100.local"/>
<param name="outbound-proxy" value="192.168.100.25:5060"/>
<param name="register-proxy" value="192.168.100.25:5060"/>
<param name="username" value="812345674"/>
<param name="password" value="812345674pwd"/>
<param name="expire-seconds" value="1800"/>
<param name="register" value="true"/>
<param name="ping" value="120"/>
<param name="contact-in-ping" value="false"/>
<param name="908-retry-seconds" value="30"/>
</params>
<variables>
<variable name="cm_context" value="incoming"/>
<variable name="absolute_codec_string" value="PCMU,PCMA"/>
<variable name="codec_string" value="PCMU,PCMA"/>
</variables>
</gateway>

2. use a fake DNS resolver or create a firewall rule to block DNS resolution.

3. Try to regiser.

Expected behavior
Register to the IP address.

Found that the dns resolution is from sofia_reg when trying to match a gateway.

applying this diff to try to match only IPs before trying to resolve DNS hostname.
