Speed up Lambda jar upload using AWS TransferManager

[mhjort]

AWS TransferManager will upload big files asynchronously in multiple parts. It also supports upload progress. See more from here: http://docs.aws.amazon.com/AmazonS3/latest/dev/HLuploadFileJava.html

@mhjort this would be an excellent enhancement indeed; do you have this on your own roadmap, or would you be needing assistance on this? Do you consider pull requests?

I was planning to implement this some day. However, have not had time yet. Lately my main focus has been on refactoring so that this tool could support both Leiningen and Boot. So yes, PR would be really welcome.

I've been looking into this, think it might be straightforward. I have a PR to update some project dependencies first which I'll be generating soon beforehand.
