Add a 'Maintenance mode' to the server #37
Description
This is a feature request.
When you have multiple users, it could be really useful when wanting to update the Go.Data server, to be able to activate a temporary 'Maintenance mode'.
(For instance by using a command like godatactl maintenance on)
The server would then serve on all https://<your-godata-server>/* a basic static html page informing the users that the website is in maintenance, and hence prevent any user to update the data while the dev team can work on updating the application.
Once the dev team is finished, then you can deactivate the maintenance mode, and the usual urls are available again.
(For instance by using a command like godatactl maintenance off)
This exists for application based on Laravel, as well as for Nextcloud.
