Add parameter to specify checkpoint archive compression
The checkpoint archive compression was hardcoded to `archive.Gzip`.
There have been requests to make the used compression algorithm
selectable. There was especially the request to not compress the
checkpoint archive to be able to create faster checkpoints when not
compressing it.
This also changes the default from `gzip` to `zstd`. This change should
not break anything as the restore code path automatically handles
whatever compression the user provides during restore.
