[MESOS-2623] Report correct states of (used|offered)Resources of master::Framework for state.json

Description

Non-scalar resources currently cannot be safely summed up across multiple slaves. Refer to MESOS-2373 for more details. usedResources and offeredResources in master::Framework are examples of this, and we expose them via master's state.json. We should try to avoid reporting incorrect state. One idea would be to strip the non-scalar resources and report scalar resources only.
