Naz	244e2374d3	Refactored maintenance app to be a class with DI ... refs #12568 - DI pattern through constructor allows for very clear separation of concerns and makes it easy to extract the class into a separate module	2021-02-02 16:11:35 +00:00
Naz	7d9f056e9b	Added error handling and response formatting in maintenance	2021-02-02 16:11:35 +00:00
Naz	d60e36ab57	Added "maintenance" app serving 503 page ... refs #12568 - When the server is in maintenance mode (e.g. during migration) it needs to serve a 503 page. Previously this role was delegated to the "frontend" which tightly coupled server bootup and frontend. - With a dedicated HTTP application serving up 503 server is no longer coupled to the frontend during maintenance	2021-02-02 16:11:35 +00:00
