Code actions support

Hi there!

I'm looking to replace a plugins use of the Facebook package with this suite and I noticed that when declaring the hyperclick usage the behaviour seems slightly different.

With that version of hyperclick it seems that it also handles the code-actions support too, I've played around trying to see if I can get code-actions to work based on [the docs](https://atom-community.io/api/code-actions/) and some other packages like ide-typescript but I think ultimately this isn't supported in atom-ide-base/related packages?

Is the code-action support planned (maybe related to https://github.com/atom-community/atom-languageclient/pull/139) or is the recommendation to use https://github.com/steelbrain/intentions instead?

Start with the Atom code-actions API documentation and the related atom-languageclient pull request #139, then compare the existing hyperclick behavior with packages such as ide-typescript and intentions. Done would require a decided approach for exposing LSP code actions, rather than only determining whether the feature is planned.
