Request timeout as a configurable parameter

[antomach-te]

This is more of a question than a feature request, as I've searched through the code but didn't find specific info on this. The underlying AWS CLI SDK accepts timeout flags for requests (--cli-read-timeout / --cli-connect-timeout , both defaulting to 60s). When running a Manager.Sync() operation, is there a way to specify the timeout? Is there a default being used (say that I'm running a sync operation for the first time of a directory with a number of fairly large files) - will Manager.Sync() time out after some time (and, if so, which time length specifically)? Can it be configured to do so?

Objective

For general use involving remote calls, having a timeout parameter can even be considered necessary.

Deliverables

Expose a timeout param in the public API that relays the config to the underlying AWS Golang SDK.
