Figure out way to share redux selectors/dispatch or other common code

[elstonayx]

Right now, we have some code in the React frontend app that might be required to be shared with the closed source portion of any codebase (e.g. selectors, dispatches, slices, or helpers). These pieces of code should only be maintained from one end so as to improve consistency.

We should figure out a way such that such code can be shared from both the open source and the closed source world.
