Description

Currently, the MasterInfo PB only supports an ip field as an int32.

Beyond making it harder (and opaque; open to subtle bugs) for languages other than C/C++ to decode into an IPv4 octets, this does not allow Mesos to support IPv6 Master nodes.

We should consider ways to upgrade it in ways that permit us to support both IPv4 / IPv6 nodes, and, possibly, in a way that makes it easy for languages such as Java/Python that already have PB support, so could easily deserialize this information.

See also MESOS-2709 for more info.
