[Apiman-user] Production guide

[Eric Wittmann]

Marc is currently working on an export/import feature that should solve 
the use-case of backing up and restoring.

There is currently no way to force a re-publish of a service, so if you 
back up your DB but not the data in Elastic, you'll have a problem.

I am planning on adding such a feature (force a re-publish) but it 
doesn't exist yet.
