CLOUDSTACK-8843: Fixed issue in default iptables rules on shared network VROn basic zone share network VR default iptables rules are not applied correctly. Due to this ssh to VR got failed.
In shared network the VR type is 'dhcpsrvr' not router. So corrected it in the ''del_standard' method to select the correct type.

Testing:
1. VR is deployed correctly.
2. Tested restart, stop, start VR.
3. New VM deployment is success.
4. ssh to VR from the host is successful.
5. iptables rules on the VR came up correctly.
below is the output from the VR:
iptables -L INPUT -nv
