* v2: support virtual port in Service port references
In addition to Service target port references, allow users to specify a
port by stringified virtual port value. This is useful in environments
such as Kubernetes where typical configuration is written in terms of
Service virtual ports rather than workload (pod) target port names.
Retaining the option of referencing target ports by name supports VMs,
Nomad, and other use cases where virtual ports are not used by default.
To support both uses cases at once, we will strictly interpret port
references based on whether the value is numeric. See updated
`ServicePort` docs for more details.
* v2: update service ref docs for virtual port support
Update proto and generated .go files with docs reflecting virtual port
reference support.
* v2: add virtual port references to L7 topo test
Add coverage for mixed virtual and target port references to existing
test.
* update failover policy controller tests to work with computed failover policy and assert error conditions against FailoverPolicy and ComputedFailoverPolicy resources
* accumulate services; don't overwrite them in enterprise

xRoute resource types contain a slice of parentRefs to services that they
manipulate traffic for. All xRoutes that have a parentRef to given Service
will be merged together to generate a ComputedRoutes resource
name-aligned with that Service.
This means that a write of an xRoute with 2 parent ref pointers will cause
at most 2 reconciles for ComputedRoutes.
If that xRoute's list of parentRefs were ever to be reduced, or otherwise
lose an item, that subsequent map event will only emit events for the current
set of refs. The removed ref will not cause the generated ComputedRoutes
related to that service to be re-reconciled to omit the influence of that xRoute.
To combat this, we will store on the ComputedRoutes resource a
BoundResources []*pbresource.Reference field with references to all
resources that were used to influence the generated output.
When the routes controller reconciles, it will use a bimapper to index this
influence, and the dependency mappers for the xRoutes will look
themselves up in that index to discover additional (former) ComputedRoutes
that need to be notified as well.
