Launching tasks with image defined entrypoint

[keis]

By default mesos will prefix the command with /bin/sh -c and ignore the entrypoint specified in the image. It's possible to tune this in the CommandInfo

I suggest we follow marathons convention of differentiating between the two modes by the field used cmd or args. https://mesosphere.github.io/marathon/docs/native-docker.html (Command vs Args)

Just to clarify, given that

ENTRYPOINT ["echo"]
CMD ["hello"]

Example 1:

{
    "cmd": "ping"
}

should result in: sh -c ping

Example 2:

{
    "args": ["ping"]
}

should result in: echo ping
