Resolves#37192
Separating generic endpoint_utils middleware logic from domain-specific
business logic. New bounded contexts would share the generic logic and
implement their own domain-specific logic. The two approaches used in
this PR are:
- Use common `platform` types
- Use interfaces
In the next PR we will move `endpointer_utils`, `authzcheck` and
`ratelimit` into `platform` directory.

Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
