Have a list of services needed for each application, and only display performance degradation banner if one of them is down.

[amprokop]

VVA stability is not high, and although we don't use it for any Caseflow app, we'll currently display the performance degradation banner for it. We should manually list dependencies for each application, and only display the banner if one of those dependencies is reporting an outage.

Certification's dependencies:
BGS, VBMS, VACOLS

Reader's dependencies: VBMS, VACOLS

Hearing Prep's dependencies: VACOLS

Dispatch's dependencies: BGS,VBMS, VACOLS

See dependencies_report_service.rb and dependencies_check_job.rb for existing code to leverage.

@nemodjuric @amprokop Is there something to do here to shut off dependancies to produce a degradation banner or do I just wait for something to go down?

Blocked due to inability to test.

So after all the work that @nemodjuric trying to get a service to go down, BGS AddressService went down on its own.

PASSED

Validated: UAT | Chrome

Steps to Validate:

1. Check monitor for a down service (in this case BGS AddressService)
2. Verify that the product that is dependent on that service (Certification) has a degradation banner
3. Verify that the common pages (help) also have a degradation banner
4. Verify that other products that don't use the service are up without a degradation banner (Dispatch, Reader).
