[Seven] - Global app state

[sneridagh]

Important

If you are not a member of the Volto Team or Developers Team in the Plone GitHub organization, then do not work on or comment on this issue.

We used Redux to have a global store in the past to keep app state and subscribe components to store changes.
Nowadays, there are more human, less verbose and usable libraries that accomplish the same, and are more performant and configurable and flexible at the same time.
