- Don't use `request.env['omniauth.params']` if it isn't present.

- Remove the `saml` section from the `gitlab.yml` test section. Some tests
  depend on this section not being initially present, so it can be overridden
  in the test. This MR doesn't add any tests for SAML, so we didn't really need
  this in the first place anyway.

- Clean up the test -> omniauth section of `gitlab.yml`

- Disable an ESLint check rather than work around it (by
  converting `OAuthRememberMe` from a regular class to a
  static class.

- Scope `$` calls inside `OAuthRememberMe`

- Change double quotes to single quotes.
- Why is `OmniAuth.config.full_host` being reassigned in the integration test?
- Use `map` over `map!` to avoid `dup` in the `gitlab:info` rake task
- Other minor changes

- The test for `rake gitlab:env:info` executed the rake task, which mutated the
  list of omniauth providers, breaking subsequent tests relying on this list.

- I've changed the rake task to duplicate the providers list before modifying it.

- I tried to get this to work by stubbing out portions of the config within the
  test. This didn't work as expected because Devise/Omniauth loaded before the
  stub could run, and the stubbed config was ignored.

- I attempted to fix this by reloading Devise/Omniauth after stubbing the
  config. This successfully got Devise to load the stubbed providers, but failed
  while trying to access a route such as `user_gitlab_omniauth_authorize_path`.

- I spent a while trying to figure this out (even trying
  `Rails.application.reload_routes!`), but nothing seemed to work.

- I settled for adding this config directly to `gitlab.yml` rather than go down
  this path any further.

- Added saml, authentiq, cas3, and auth0
- Crowd seems to be a special case that will be handled separately.

- There was previously a test for `saml` login in `login_spec`, but this didn't
  seem to be passing. A lot of things didn't seem right here, and I suspect that
  this test hasn't been running. I'll investigate this further.

- It took almost a whole working day to figure out this line:

    OmniAuth.config.full_host = ->(request) { request['REQUEST_URI'].sub(request['REQUEST_PATH'], '') }

  As always, it's obvious in retrospect, but it took some digging to figure out
  tests were failing and returning 404s during the callback phase.

- Test all OAuth providers - github, twitter, bitbucket, gitlab, google, and facebook

- Pass a `remember_me` query parameter along with the initial OAuth request, and
  pick this parameter up during the omniauth callback from
  request.env['omniauth.params']`.

- For 2FA-based login, copy the `remember_me` param from `omniauth.params` to
  `params`, which the 2FA process will pick up.

- For non-2FA-based login, simply call the `remember_me` devise method to set
  the session cookie.
