commit 1dde9531104415c7759ebc1fb560bb55e16bbd8b

Added a helper for capability filtering in the allocator.
`isCapableOfReceivingAgent(` returns whether a framework is capable
of receiving any resources on the agent.

Updated `Slave::getAvailable()` to return all shared resources.
Currently, `HierarchicalAllocatorProcess::Slave::getAvailable()`
only exposes the unallocated portion of shared resources. However,
we currently always consider a copy of shared resources to be
available for allocation.
This helps us acheive some cleanup of one-off shared resources logic
in the allocation loop.

Added a `stripIncapableResources` helper in the allocator.
This helper removes any resources that the framework is not
capable of receiving based on the given framework capability.

> Project: Mesos
> Issue Type: Improvement
> Components: allocation
> Reporter: Meng Zhu
> Assignee: Meng Zhu
> Priority: Major
> Labels: mesosphere
>
> - Add a function for returning the subset of frameworks that are capable of
> receiving offers from the agent. This moves the capability checking out of
> the core allocation logic and means the loops can just iterate over a smaller
> set of framework candidates rather than having to write 'continue' cases.
> This covers the GPU_RESOURCES and REGION_AWARE capabilities.
> - Similarly, add a function that allows framework capability based filtering
> of resources. This pulls out the filtering logic from the core allocation
> logic and instead the core allocation logic can just all out to the
> capability filtering function. This covers the SHARED_RESOURCES,
> REVOCABLE_RESOURCES and RESERVATION_REFINEMENT capabilities. Note that in
> order to implement this one, we must refactor the shared resources logic in
> order to have the resource generation occur regardless of the framework
> capability (followed by getting filtered out via this new function if the
> framework is not capable).
