When using an older or newer gfsh to connect to an older or newer distributed system gfsh will throw a warning error and not connect.
Example warning message Cannot use a 9.8.5 gfsh client to connect to a 9.9.0 cluster..
The desired behavior is to allow gfsh connect and only if there is an issue with an updated /unknown command parsing should the system throw an error and provide the extra guidance of what version the servers are at and the version of the current gfsh cli.
Initially add these capability into the newer product version
Later based on the feasibility of adding this to older version, this will be ported into the older version.
