> Define and implement the following protocols and protocol messages using protobufs:
> * ClientSCMProtocol - The protocol between the yarn client and the cache manager. This
protocol controls how resources in the cache are claimed and released.
> ** UseSharedCacheResourceRequest
> ** UseSharedCacheResourceResponse
> ** ReleaseSharedCacheResourceRequest
> ** ReleaseSharedCacheResourceResponse
> * SCMAdminProtocol - This is an administrative protocol for the cache manager. It allows
administrators to manually trigger cleaner runs.
> ** RunSharedCacheCleanerTaskRequest
> ** RunSharedCacheCleanerTaskResponse
> * NMCacheUploaderSCMProtocol - The protocol between the NodeManager and the cache manager.
This allows the NodeManager to coordinate with the cache manager when uploading new resources
to the shared cache.
> ** NotifySCMRequest
> ** NotifySCMResponse
