Support Rails 6.1

[JonRowe]

This branch will become the root of Rails 6.1 development. The plan would be to launch this as a new version when Rails 6.1 is released, likely a major version as Rails versions supported will change.

Edit This will not be merged until we are ready to release the next version, it will be used as an available branch for those working on 6.1.

Todo:

• View specs have changed behaviour surrounding helper modules, investigate and fix.
• A controller spec has a broken config somehow
• Generated controller spec "uploads" fails

Looks good.
I've missed the last build results, wondering how many things are broken.

I do not understand why it is not able to find 3.10.0.pre. I have no issue locally to find them.

Using rspec 3.10.0.pre from source at `/Users/bti/code/rspec-dev/repos/rspec`

To test the CI, I switched 4012de7

@benoittgt @pirj My intent for this branch is to use it as dev / maintenance root branch so could you PR to it rather than push commits directly, especially for WIP commits...

(I really don't want force pushing to happen to this branch, as I want it available to be used by people running Rails 6.1 from git)

[JonRowe]

@benoittgt I'm going to unpick your commits to a PR, from now on can everyone PR to this branch and that should be the last force push

I just lauch a CI build for Rails v6.1.0.rc2 https://github.com/rspec/rspec-rails/actions/runs/396008092

Edit: success ✅ https://github.com/rspec/rspec-rails/actions/runs/396108630

Ok. 3 commits need to be cherry pick if we want to make it workable rails-6-1-dev...rails-6.1.0.rc2-dev

1. 05f3a2c
2. 7300e06
3. 5737b93

We will still have the current issue in the CI with Rails master and dependencies resolving. Should we have rails-6.1.0.rc2 + rails master in the CI for this branch?

Should we have rails-6.1.0.rc2 + rails master in the CI for this branch?

Sure, why not both? As long if we don't set required for those that consistently fail.

Yes I am in favor of both.

Rails 6.1 has been released. I just updated to CI and if CI is good for #2408 I think we should release.

I will look at #2410
