Support e2e tests against multiple NetBox versions

[henrybear327]

(Reopen #167. Due to PR base branch setting errors, I can't reopen the original PR...)

Since we are introducing the e2e test and running against real NetBox instances, it makes sense to test against different versions of NetBox, so we can flag issues early on.

CI will now run all e2e tests against the supported versions.

The supported NetBox versions are (the latest patch version for the major.minor release):

• 3.7.8
• 4.0.11
• 4.1.8

Instead of create-kind, we now have create-kind-3.7.8, create-kind-4.0.11, and create-kind-4.1.8. The same goes for make test-e2e.

The patching mechanism is used to apply database schema fixes and demo data version changes. When we introduce support for new versions, usually only the database schema would need to be changed.

Blocked by #175 (#177)

To test this locally, execute make test-e2e-4.1.8 (or other supported versions)

@alexandernorth PTAL thank you :)

I think this is ok to merge as it is, but we should probably revisit the best way to handle multiple version services in the future

I will create an issue to track this.

Thank you @alexandernorth :)
