Publisher and subscriber clients consist of a tree of services, where the leaf services wrap gRPC streams. When errors are propagated to the top-level publisher/subscriber clients, the context may be ambiguous (e.g. RPC errors) and not helpful for debugging.
This PR wraps errors in the leaf services, e.g.
publisher(/projects/project-id/locations/zone/topics/topic-id/partitions/1): %w.golang.org/x/xerrorsis used because error wrapping/unwrapping is supported from Go 1.13 onwards. Once we drop support for 1.11, we can just use the standard library.
