Subject: [PATCH 20005/20007] [Storage] add btrfs_compression option

This is a new option to allow specifying the compression algorithm and

level for Btrfs filesystems. If set, it will be passed to Blivet and

applied when mounting Btrfs filesystems.

Default this to None, but set it to "zstd:1" for CentOS Stream Hyperscale.

(cherry picked from commit 15e06b6aa9876d55dedaa9c37f2f589361de8949)
