I think this should have removed deliveryservices_required_capabilities from API v5 but it doesn't appear to have done that.

[ocket8888]

This now removes deliveryservices_required_capabilities, but doesn't update the documentation to reflect that.

The new field of a Delivery Service should also be represented in the Delivery Service Overview section.

@srijeet0406 TestDeliveryServicesRequiredCapabilities is entirely commented out

trafficcontrol/traffic_ops/testing/api/v5/deliveryservices_required_capabilities_test.go

Lines 28 to 31 in 3192836

	//func TestDeliveryServicesRequiredCapabilities(t *testing.T) {
	// WithObjs(t, []TCObj{CDNs, Types, Tenants, Users, Parameters, Profiles, Statuses, Divisions, Regions, PhysLocations, CacheGroups, Servers, ServerCapabilities, Topologies, ServiceCategories, DeliveryServices, DeliveryServiceServerAssignments, ServerServerCapabilities, DeliveryServicesRequiredCapabilities}, func() {
	//
	// currentTime := time.Now().UTC().Add(-15 * time.Second)

Also, the API tests still try to create and delete DS required capabilities.
