.New ways to identify client versions
This update adds the following features that help with identifying client versions to determine which clients use an old version of Red Hat Ceph Storage.
* The `ceph osd set-require-min-compat-client` command adds the ability to set a minimum required release for clients to prevent new connections from older clients. By default it is set to `jewel`. To view its value, use the `ceph osd dump` command.
* The `ceph features` command that reports the total number of clients and daemons and their features and releases.
* If the debugging level for Monitors is set to `10` (`debug mon = 10`), addresses and features of connecting and disconnecting clients are logged to log file on a local file system.
