Title: [CHEF-3611] Add ability to download from private AWS S3 buckets

Introduce new URL scheme s3:/// for :recipe_url
that will trigger signing mechanism and convert link to https://
scheme. One could use s3:// or any other valid S3 endpoint,
like s3-eu-east-1://

Required configuration variables are:
'aws_access_key_id' and 'aws_secret_access_key' - your credentials
for secured S3 bucket.
