adding rsockets support into JDK

[Lu, Yingqi]

Hi Brian,

Thank you for testing it out. It seems like the tests have issues handling the environment that does not have RDMA devices.

I will look into this and get back to the mailing list by Monday.

Thanks,
Lucy

With the above changes, all test cases pass on my Linux CentOS 7 box.

I get the failures [1, 2] when this version is run on my local build (Ubuntu 18.04 VM).

Thanks,

Brian
