VertexParams in auth-types holds the vertex_* fields of CredentialLiteLLMParams
in both spellings, with one ParamSpec per setting: the wire names, the litellm
module global VertexBase.get_vertex_ai_* consults, and the environment names.
A credential deserializes from text or the JSON object a config spells, an
empty object counts as absent, and both credential fields are redacted in
Debug. auth-gcp is split so lib.rs is the entrypoint (config, auth,
constants), its lookups resolve through the specs, secret_names() derives
from them, and get_vertex_ai_project_from_credentials reads a service
account's project_id for hosts that need it before a token exchange. The OCR
host folds the module globals in by spec at projection, so OcrSettings no
longer carries vertex_project and vertex_location.
Move the shared test helpers out of litellm-inference's test-support
feature into a publish = false litellm-inference-testing crate used only
as a dev dependency by the format crates.
Also drop the dead src/constants.rs (OPENAI_DEFAULT_API_BASE had no
users) and declare the litellm-http/litellm-llms test-support features
on the crates that actually use them instead of relying on feature
unification through litellm-inference's dev-dependencies.
