Sync backends data to MailChimp

[patrickvenetz]

Bug Report

When re-subscribing a user by force on MailChimp itself, it may lack information e.g. name or Customer groups.

Steps to Reproduce

1. Re-subscribe a user via MailChimp form (check with Customer Support for details)

Actual Results

Name or Customer groups might be incorrect.

Possible Solutions

Add a link to «enforce» backends data to be synced to MailChimp after re-subscribing a user.

Wouldn't the alternative be to force re-sub via API (Patte always says it possible). Or listening to the web hook?

Asking the support team to manually do it also seems error prone.

I am under the impression of quite the opposite: Resubscribing is not working via API. This eventually led to using that MailChimp form. If that does however work, that would be the way to go.

Acting on MailChimp web hooks is a good idea, and I'd prefer that second.

Syncing mutation is cheapest as it boils down to wiring existing libraries (basically exposing enforceSubscriptions) and a mutation link in this repository.

@patte I remember you saying something about force re-sub via API. Did we ever check if that works?
