Add action creator for RSAA action

[artursvonda]

Created action creator for cleaner boundary for RSAA actions.
This abstracts shape of the action away from user and allows. And it allows to add validation to action creation process if we choose to (which can be dev build only thing).

This will also allow for nicer and cleaner typings for Typescript.

Coverage remained the same at 100.0% when pulling 3b63f2a on artursvonda:action-creator into 6e782cd on agraboso:master.

Hi @artursvonda, thanks for the contribution! This looks reasonable.

Would you mind adding some documentation about this?

Will do

[artursvonda]

Rewrote docs to use createAction as the preferred way to create RSAA actions.

Should RSAA be marked with some JsDoc annotation? Like @private or @deprecated to discourage it's usage?

Yeah, makes sense. Will add that. If we want to remove the export in some future version, we should @deprecated to indicate that it be removed. If we want to keep it there but discourage, @private makes sense.

I think it makes sense to remove it as long as all use-cases are handled without it. And the only use-case I can think of, that is not yet handled, is getting options from action. But that can be added later if required.

Done
