Support setting object acl

[Gitii]

Hi,

I am using scaleway object storage for my buckets. By design, scaleway will set the acl of all objects to private. It's possible to change the acl later (for example using the web console or the aws s3 cli). It would be great if sleet could set the acl during upload.
There could be an optional config option (if set, the specified acl will be set) or a command arg.
I dug through the codebase a bit, but I failed to find a good starting point, otherwise I would have tried to create a PR.

Thanks!

This sounds like a great feature for Sleet.

I suggest going with an optional config value as you mentioned. Those can also be passed via env vars or from the command line, see: Here is where S3 files get created from the S3 filesystem:

Sleet/src/SleetLib/FileSystem/AmazonS3FileSystem.cs

Line 120 in 610cb10

return new AmazonS3File(this, pair.Root, pair.BaseURI, LocalCache.GetNewTempPath(), _client, _bucketName, key, _serverSideEncryptionMethod, _compress);

The ACL could be applied during the upload here:

Sleet/src/SleetLib/FileSystem/AmazonS3FileSystemAbstraction.cs

Line 126 in 610cb10

public static async Task UploadFileAsync(

Here is where S3 files get created from the S3 filesystem:

Sleet/src/SleetLib/FileSystem/AmazonS3FileSystem.cs

Line 120 in 610cb10

return new AmazonS3File(this, pair.Root, pair.BaseURI, LocalCache.GetNewTempPath(), _client, _bucketName, key, _serverSideEncryptionMethod, _compress);

The s3 filesystem which would have the LocalSettings for the config is here:

Sleet/src/SleetLib/FileSystem/FileSystemFactory.cs

Line 93 in 610cb10

else if (type == "s3")
