Tests against different activerecord/activesupport versions

[Aqualon]

Currently tests don't run against different activerecord versions, but just assumed everything is like in activerecord 5.

• Use released appraisal gem, issue for using from github.com was released in 2.5.0
• Test against 43 different activerecord versions [6.1.7.8, 7.0.8.4, 7.1.3.4] (7.2.0 fails currently, so would only enable it together with the fix)
• Use appraisal generate to avoid installing all gem versions on all builds
• Can we move out the go tests, since they are independent of the ruby/redis/activerecord matrix? Currently they run on all of them we can't, because failover tests require beetle binary created in the go step

@danielgoncharov @david-krentzlin what do you think of this? Not sure about the cost side, with additional checks against activerecord versions we would end up with 3 * 2 * 4 = 24 checks eventually.

@Aqualon Yeah, I think it is a good idea and since they should run in parallel I see no problem at all. Wondering if we want this for activesupport as well.

[jojahner]

It would also not increase the number of combinations, since they should come with the same version. @Aqualon What do you think?

[Aqualon]

activerecord always comes with activesupport as dependency in the same version. But maybe we should make it more explicit in the Appraisals/workflow, define rails_versions and then add activerecord and activesupport in the appraise block?

[jojahner]

Ah, yeah true. I would make it explicit, and do it as you said. Define the ruby version and then add activerecord and activesupport.

[Aqualon]

@jojahner if it's fine for you, please approve/merge it. I'd then open another PR for the 7.2.0 adaptations

Cool, thank you! ❤️
