ENH: Injectable GridField config components.

Description

Allow GridField config components to be injectable so we have more configuration options.

Issues

• GridField config doesn't use Injector to create components #1327

Note

Failing tests are an upstream error, not related to this changeset.

Pull request checklist

• All commits are relevant to the purpose of the PR (e.g. no debug statements, unrelated refactoring, or arbitrary linting)
  • Small amounts of additional linting are usually okay, but if it makes it hard to concentrate on the relevant changes, ask for the unrelated changes to be reverted, and submitted as a separate PR.
• The commit messages follow our commit message guidelines
• The PR follows our contribution guidelines
• Code changes follow our coding conventions
• This change is covered with tests (or tests aren't necessary for this change)
• Any relevant User Help/Developer documentation is updated; for impactful changes, information is added to the changelog for the intended release
• CI is green

Thanks for the PR @mfendeksilverstripe, can you check if the failing test is related? There's some deprecation warnings there. Otherwise the change looks ok.

Hey @michalkleiner confirming that the broken tests are upstream error. As far as I can see they were introduced recently.

Can confirm the CI failure is unrelated to this PR.

For future reference, the commit message shouldn't have a colon

- ENH: Injectable GridField config components.
+ ENH Injectable GridField config components.

I'm okay merging this one without that small change.
