Struct OAuth2ClientCredentialsAuth 

pub struct OAuth2ClientCredentialsAuth { /* private fields */ }

OAuth2 client-credentials authentication. STATIC config; ignores inbound_token.

The token is fetched lazily from token_url on first apply and cached. The fetch uses a fresh reqwest::Client (mirrors the reference). The cached token is stored under a tokio::sync::RwLock.
