Screwdriver: feature: There is no way to announce the downtime.

[yoshwata]

What happened:
It is useful if users are able to know about the downtime from web ui. We'd like to show the message like 2018/4/2 10:00 - 11:00 : Screwdrivrer will down for maintenance at top of pages.

What you expected to happen:
Screwdriver UI can show maintenance message.

Proposal

We should add endpoints to update and delete banner messages in the Screwdriver UI. Remove, create, and update should require admin permissions (https://github.com/screwdriver-cd/screwdriver/blob/master/config/default.yaml#L31).

1. __POST__ /banners
   __body__: { message: <STRING> }
2. __PUT__ /banners/{id}
   __body__: { message: <STRING> }
3. __GET__ /banners/{id}
4. __GET__ /banners to list all banners
5. __DELETE__ /banners/{id}

Tasks

• [x] data-schema: Add a banner table and schema validation (somewhere here https://github.com/screwdriver-cd/data-schema/tree/master/models)
• [x] models: Add banner model (should be very similar to https://github.com/screwdriver-cd/models/blob/master/lib/collectionFactory.js, https://github.com/screwdriver-cd/models/blob/master/lib/collection.js)
• [x] API:
  
  
  
  • [x] Take in auth admin information
  
  
  • [x] Add endpoints in a banners folder (see https://github.com/screwdriver-cd/screwdriver/tree/master/plugins) with banners README.md
  
  
• [x] UI: Display banner on UI

Changelog

• 5/2/18 - updated endpoints

This feature is available now. SD admins can create and delete banners to be displayed in UI.
