Review request for mesos and Jiang Yan Xu.

Bugs: MESOS-6062

Repository: mesos


When static resources indicate resources with a positive size, we use
that for the resources on the agent. However, --resources can include
resources with no size, which indicates that mesos agent determine the
size of those resources from the agent and uses that information. Note
that auto-detection of resources is allowed for all known resource
types represented in JSON format only. Auto-detection is not done when
the resources are represented in text format.

With this change, JSON representation for disk resources that do not
specify any value would not result in an error, but those resources
will not be accounted for until a valid size is determined for such
resources. A scalar value of -1 still results in an invalid resource.
