feat(dl-center): add support for arbitrary acls

This commit adjusts our DownloadCenter's UploadAssetOptions to support
taking an optional 'acl' parameter. When we upload an asset to S3,
this parameter is used to set the ACL on the put request. If no acl is
set, we default to "public-read" to preserve backward compatability.
