Feature: Add option for "sync" command to use S3 Inventory manifest.json file

For the "sync" command operating with a local source path to a S3 bucket, such as "aws sync . s3://example-bucket", please add the ability to specify a path to an S3 Inventory manifest file.

For example: aws sync --inventory-manifest=s3://example-bucket/destination-prefix/source-bucket/config-ID/YYYY-MM-DDTHH-MMZ/manifest.json . s3://example-bucket

With the option present, the sync command will retrieve the Inventory list, uncompress, compare the local filesystem's files to the Inventory file, and sync the files as normal to the S3 bucket.

This benefit of this is the sync command will avoid having to run synchronous S3 API List operations for the comparisons and should result in significant sync speed up and cost reductions.
