Closes PIN-5558

Manual test

Delegate without attribute, Delegator without attribute

Delegate without attribute, Delegator with attribute

See comment below: since isMine should probably consider only the requester, while hasCertifiedAttributes should consider the requester and the consumer delegators, we can split the two params here

Suggested change

	requesterTenants: tenantApi.Tenant[]
	requesterTenant: tenantApi.Tenant,
	consumerDelegators: tenantApi.Tenant[]

I'm not sure isMine shall consider the delegators, because it's about the requester being the producer of the eservice, the one that can manage it/edit it, while if I am the delegate of a consumer delegation I want to consume the eservice. Should this maybe be set to true in the case the requester is the delegate of a producer delegation? (to discuss with the "Capofila" team, probably, as a further task).

I would also add a comment to explain why hasCertifiedAttributes checks the delegators, it's hard to understand because the name is misleading now. If you think it makes sense, let's also add the same comment as the API spec's description for the field.

Suggested change

	isMine: requesterTenants.some((t) =>
	isRequesterEserviceProducer(t.id, eservice)
	),
	hasCertifiedAttributes: requesterTenants.some((t) =>
	hasCertifiedAttributes(descriptor, t)
	),
	isMine: isRequesterEserviceProducer(requesterTenant.id, eservice),
	hasCertifiedAttributes: [requesterTenant, ...consumerDelegators].some((t) =>
	hasCertifiedAttributes(descriptor, t)
	/* True in case:
	- the requester has the certified attributes required to consume the eservice, or
	- the requester is the delegated consumer for the eservice and the delegator has the certified attributes required to consume the eservice */
	),
