--------------------------------
hi [~weichiu], pr sent, it passed all checks suggested by the CONTRIBUTING.md
guide, but I'm not sure whether it make the ssd profile for datanode really
works since I've got no ssd at my hand for test. Please help test it, thanks~

> The property hdds.db.profile (default is "DBProfile.DISK". The SSD profile is
> selectable via "DBProfile.SSD") is configurable and allows OM, SCM and Reconn
> to choose the SSD profile which optimizes for SSD.
> It's not the case for DN. DN always use the spinning disk profile for
> rocksdb. We should make it possible to choose SSD profile.
