Add Banner Deploy to Jenkins

[rosibaj]

We need to develop the alert API response to feed into the update banners:

The alert component for the platform-api expects this api response:

[{
  level: AlertLevel;
  title: string;
  message?: string;
  dismissable: boolean;
},
...]

Type AlertLevel = 'error' | 'warning' | 'info'

• ability to add the alert
• alert delivered by gateway

Implementation

We don't really need durable storage for the banner. We will use a env vriable and github:

• Have a banner information file, with the editable banner variable.
• Make a config in helm chart; job in jenkins to update the values.
• Read ENV var from ENV valu. ENV value is passed in from git thru helm.
• Jenkins rolling-restart and a job for banner deploy.

The workflow for BA or bioinformatics team to add a banner will be to make a PR to update Banner, go to jenkins and deploy button for banner job.

Expected Behavior from this ticket

• Make a Jenkins job to specifically redeploy the gateway with the banner env variable.
• WIki page with detailed on instructions on how to update the message , and example messages for emergency situations that can be used as a template.
