The goal of this PR is to test if Twenty can support a large number of
members, a question which was raised by a large company that is
considering moving away from Salesforce.
I was expecting the currentWorkspaceMembersState to cause a lot more
issue. It would be very hard to get rid of it in the context of actors,
I think that would require a big refactoring. I thought we'd have to do
it but it turns out the perf are pretty good. One thing we need to
improve is the pagination on the roles page, we'll wait for @Bonapara to
update that
