API v5 client.CreateDeliveryServicesRequiredCapability 404s

[zrhoffman]

This Bug Report affects these Traffic Control components:

• Traffic Control Client - Go library
• Traffic Ops - v5 API tests
• CDN in a Box - enroller, Traffic Ops data

What did you do?

The enroller tried to create a DS required capability using client.CreateDeliveryServicesRequiredCapability (in API v5)

What did you expect to happen?

Capability is created

What actually happened?

error creating Delivery Services Required Capability: error requesting Traffic Ops: path 'https://trafficops.infra.ciab.test:443/api/5.0/deliveryservices_required_capabilities' gave HTTP error 404 Not Found - error-level alerts: The requested path '/api/5.0/deliveryservices_required_capabilities' does not exist.

It was removed from API v5 in #7224, so these client methods should be removed:
CreateDeliveryServicesRequiredCapability
DeleteDeliveryServicesRequiredCapability
GetDeliveryServicesRequiredCapabilities

And the places using them should be updated use Delivery Services directly.
