------------------------------------------
Hi [~cxorm]
I will take up this, as internally/and our users are confused with this error.
Proposal is:
Make ratis.snapshot.dir do not depend on ozone.om.ratis.storage.dir, so that
ratis.storage.dir does not have any other directories.
And also if ratis.storage.dir is not defined, the default we fall back to
ozone.metadata.dirs, then we will have ratis.storage.dir as ozone.metadata.dirs
+ "/ratis".
And for older clusters, the directory will be moved to new ratis.snapshot.dir
