Reduce fileclient.get_file latency by merging _file_find and _file_hash
Reduce fileclient.get_file latency by merging _file_find and _file_hash

This commit uses the newly created _file_hash_and_stat master function.
This is especially useful if your master and minion servers are in another datacenter (in my case the ping latency between them is 10ms, which somehow makes it around 40ms to access full file metadata)
This time is now cut in half. Yay!
