fix: full resource names to resource names in names

[artek-koltun]

The full resource names are changed to resource names due to the following reasons:

1. HTTP gateway sends resource names in that form
2. Based on explanations from this patch: aip-dev/google.aip.dev@00e3ac7
3. Aip-122 also mentions: Resources must expose a name field that contains its resource name. (they differentiate between resource name and full resource name)

As I understand, a full resource names are used when a field refers to resources in multiple APIs and ambiguity can arise. For example, if a field can refer to a book in a library API, a product in an e-commerce API, or a user in an authentication API, just using the relative resource name could lead to confusion. In this case, the field could refer to a book ID, a product ID, or a user ID, depending on the context. And to avoid this ambiguity, the full resource name should be used when a field refers to resources in multiple APIs. The full resource name clearly indicates which API the resource belongs to, making it clear whether foo refers to a book in the library API (//library.googleapis.com/publishers/foo), a product in the store API (//ecommerce.googleapis.com/products/foo), or a user in the let's say authentication API (//auth.googleapis.com/users/foo). It shouldn't be used in Names of our resources because the requests are sent to a dedicated known service //storage.opiproject.org/

Unblocks enabling of HTTP gateway #878

Need godpu patch to pass CI opiproject/godpu#437
