Add ability to run Redis cluster tests in local development

[mostlikelee]

Goal

User story
As a contributor to Fleet server code,
I want to be able to run Redis cluster tests locally
so that I can dramatically increase velocity when working on features or bugs that utilize Redis (live queries)

Context

• Requestor(s): @mostlikelee
• Product designer: _____

This request comes after development of https://github.com/fleetdm/fleet/issues/17379 where Redis cluster tests were failing. The long iteration process involved pushing print statements to CI and waiting ~20min for results because that is currently the most viable way to get feedback on cluster tests.

@sharon-fdm I'm prioritizing this engineering-initiated story for estimation. Since it will be a straight-forward docker compose addition it should be a quick win.

[mostlikelee]

A docker compose already exists (CI is using this currently), but win/mac are excluded from running the tests because of docker desktop networking issues reported ~3yrs ago. There could be a chance Docker resolved this issue, but it may not be a trivial solution. Still worth a timeboxed effort IMO.

[sharon-fdm]

Thanks @lukeheath. SGTM.

[lukeheath]

@mostlikelee Maybe the solution is to stand up a linux VM to run the server in, and connect to it locally via ngrok?

[lukeheath]

Given there isn't an immediate need for more redis-cluster work, we may want to wait and roll this in next time we work on it.

[sharon-fdm]

Suggestion from the team: Automate a way to move dev env to Linux (e.g. EC2).
