Summary: DNS Cache and SRV Records issue

Initial Comment:
DNS Cache module does not seems to handle properly DNS SRV records.

Example:
Opensips "dns cache" perform a lookup on mydomain.com.
The DNS answers : SRV gw1.mydomain.com and gw2.mydomain.com
Then Opensips perform an "A" query to "gw1.mydomain.com"
The DNS answers 1.2.3.4 for gw1.mydomain.com.
Finaly opensips forward the SIP request to 1.2.3.4


After that, on a new SIP request, Opensips continue to forward request directly 
to 1.2.3.4 (gw1.mydomain.com) and never trie to use gw2.mydomain.com

In my point of view, there is an issue in the DNS Cache module. Opensips should 
try randomly both mydomain.com SRV records gw1.mydomain.com and gw2.mydomain.com
