Using sha1 hashes as filenames about aws

[Bladrak]

To comply with the best practices, we should rather suggest that the user uses CloudFront as in http://docs.aws.amazon.com/AmazonS3/latest/dev/request-rate-perf-considerations.html#get-workload-considerations, given the workload should rather be GET-request intensive (as the cache is only written once).

The suggestion of adding an hash as a key prefix (not the full key) is rather for a mix of request types (GET but also PUT/POST/DELETE), which may be the case in some implementations of thumbor, but is rather limited IMO. The option could be added though, for those implementations, to add a hash prefix to the file key.

I suppose UUID key usage on POST requests is enough chaotic.
Problem exists on loader + storage when very heavily used as @Bladrak suggests.
