[Evergreen-dev] Redis relicensing

[Bill Erickson]

Well, if we need it, KeyDB does appear to be a drop-in replacement.

I had an EG+Redis instance running on Ubuntu 22.04.

* Stopped Evergreen
* Stopped redis-server
* Installed KeyDB (https://docs.keydb.dev/docs/ppa-deb)
* Modified /etc/keydb/keydb.conf to disable disk persistence (save = "")
* Restarted keydb-server
* Restarted Evergreen
* Poked around... no issues.

The only unexpected bit was that the environment variables are still
Redis-branded.  E.g.

$ REDISCLI_AUTH=<password> keydb-cli

-b
