> allow GFSH to connect to newer and older locator/server.

> Key: GEODE-8331
> URL: https://issues.apache.org/jira/browse/GEODE-8331
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Reporter: Jinmei Liao
> Priority: Major
> Labels: GeodeOperationAPI, pull-request-available
>
> 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.
