Qu Wenruo d4f4d7b76e btrfs-progs: tune: add --convert-to-free-space-tree option
From the very beginning of free-space-tree feature, we allow mount
option "space_cache=v2" to convert the filesystem to the new feature.

But this is not the proper practice for new features (no matter if it's
incompat or compat_ro).

This is already making the clear_cache/space_cache mount option more
complex.

Thus this patch introduces the proper way to enable free-space-tree, and
I hope one day we can deprecate the "space_cache=" mount option.
