This patch introduces new configuration file parameters,
POST_SCRATCH_MKFS_CMD and POST_SCRATCH_POOL_MKFS_CMD.
Usage example:
POST_SCRATCH_MKFS_CMD="btrfstune -m"
POST_SCRATCH_POOL_MKFS_CMD="btrfstune -m"
Can't we add extra options for mkfs.btrfs to support metadata uuid at
mkfs time?
We already support quota and all other features, I think it would be
much easier to implement metadata_uuid inside mkfs.
If this feature is only for metadata_uuid, then I really prefer to do it
inside mkfs.btrfs.
Thanks,

With this configuration option, test cases using _scratch_mkfs(),
scratch_pool_mkfs(), or _scratch_mkfs_sized() will run the above
set value after the mkfs operation.
Other mkfs functions, such as _mkfs_dev(), are not connected to the
POST_SCRATCH_MKFS_CMD.
