Questions about Dovecot push notifications

[Ralf Becker]

I managed to figure out some of my questions and answer them here I case
someone else runs into them:

Yes, metadata get's replicated, you even have to create the metadata
configuration on both replication nodes, otherwise the replication stops!

That allows to store eg. your push token in the user attribute Dovecot
sends out.

You have to specify user_from_metadata in push_notification_driver.

As get and set metadata is a regular IMAP command that should work,
thought I don't use it currently.
