RFR 8047031: Need new tests to check socket permission

[Amanda Jiang]

Hi All,

Could you please review 1 new test to be added for SocketPermission.
New test is added to check socket permissions, for instance -
- java.net.SocketPermission with "connect", "resolve", "accept", "listen"
with Socket, DatagramSocket, MulticastSocket etc.

JDK Issue: https://bugs.openjdk.java.net/browse/JDK-8047031
WebRev: http://cr.openjdk.java.net/~rhalade/8047031/webrev.00/

Thanks,
Amanda
