Add ability to select storage class when backing up to Amazon S3

[Hannnes1]

Is there an existing feature request for this?

• [X] I have searched the existing issues before opening this feature request.

Describe the feature you would like to see.

I would like to be able to select the storage class for backups that are made to Amazon S3. Right now, the default storage class (standard) is used, which results in the monthly price being considerably higher than needed.

Describe the solution you'd like.

I would like to be able to set the storage class as an environment variable, in the same that the other backup options are set.

As for how to implement it, it should be enough to add the header x-amz-storage-class in the API request to Amazon.
