Add new latency samples for GetValue, GetRange, QueueWait, and VersionWait

[neethuhaneesha]

cherry-pick of #8173

4 new latency samples are added to StorageServer reads

ReadValueLatency - total request to response latency for GetValue requests, measured the same was as the generic ReadLatency
ReadRangeLatency - total request to response latency for GetKeyValues requests, measured the same was as the generic ReadLatency
ReadQueueWaitLatency - delay between request receipt and when it starts executing after any execution or queuing delays
ReadVersionWaitLatency - delay after QueueWait caused by waiting for the storage server to receive the data version necessary for the read
So far, nothing is added to these new latency samples for Streaming Range Read requests.
