Add support for transfer acceleration without the need of fully custom managed bucket

[msfstef]

Background

I can't deploy some of my projects with serverless' --aws-s3-accelerate option enabled as the S3 bucket is by default not transfer acceleration enabled. I noticed there is a manageResources flag for a fully custom S3 bucket where I could enable the transfer acceleration but would have preferred to keep everything default and out of the box ready.

Proposed changes

Unless this bloats the library too much I figured the transfer acceleration could be added as an option.

I will try to review and test this in the upcoming weeks if you want to help us shorten the feedback cycle can you please rebase this off of master and test it out with serverless 3 ?
