mesos ps not working with mesos 0.16

[Eric Lee]

Trying to run a mesos ps after configuring my ~/.mesos.json file against a mutli-master setup yields the following:

$ mesos ps
Traceback (most recent call last):

Taking a peek at master.py:72 the mesos.interface package is trying to parse the master value returned from the zk node:

            info = mesos.interface.mesos_pb2.MasterInfo()
            info.ParseFromString(data)

in this case data has a value of master@10.12.13.14:5050

My .mesos.json looks like this:

{
    "default": {
        "log_level": "warning",
        "log_file": null,
        "master": "zk://10.12.13.14:2181,10.15.16.17:2181,10.18.19.20:2181/mesos"
    },
    "profile": "default"
}

Should be fixed now. Reopen if I didn't get it the first time =)
