Decouple server and client versions #962
Description
The zowe.org download page currently groups all the core Zowe components, and some Zowe extensions, into a single logical release, and displays them with this grouping in the v2 historical release table. We're thinking of moving towards more independent release cycles for Zowe components, so client and server components may release at different times, have different versions, and different histories. The download page needs to be updated to support decoupled release scenarios.
