Update versioning strategy

[madolson]

Initial attempt at laying out what we need to print out versions in various places.

Update server info, module info, and lua info to print out information about our version along with our redis compatibility. Redis_version will be fixed at 7.2, while server version will continue to increment. We also add a new info field, sever_name which will always point to the eventual name of our project.

This also starts including the server-info in the RDB aux field. This currently double prints the info (one for redis and one for server) this seems ok for now.

Also added a lightweight versioning layer in redis-cli, to check first server_verion then redis_versin.

I also added a change for a hiredis test (which afaik we don't use anywhere).
