in7952200c, we changed the `selected_format` from `mc` to `me`, but to be backward compatible the cluster starts with "md", so when the nodes in cluster agree on the "ME_SSTABLE_FORMAT" feature, the format selector believes that the node is already using "ME", which is specified by `_selected_format`. even it is actually still using "md", which is specified by `sstable_manager::_format`, as changed by54d49c04. as explained above, it was specified to "md" in hope to be backward compatible when upgrading from an existign installation which might be still using "md". but after a second thought, since we are able to read sstables persisted with older formats, this concern is not valid. in other words,7952200cintroduced a regression which changed the "default" sstable format from `me` to `md`. to address this, we just change `sstable_manager::_format` to "me", so that all sstables are created using "me" format. a test is added accordingly.
