Add per-Connection authentication so CDH 5 / Kerberos / HTTP Basic clusters can be queried. - auth_type: none / simple / basic / kerberos - auth_user / auth_password for HTTP Basic - auth_principal / auth_keytab stored for audit/display; actual SPNEGO handled by httpx-kerberos using the system Kerberos credential cache - YarnClientConfig.auth_for_httpx() returns the right httpx.Auth object - _request passes auth= through to httpx.request alongside verify= New dependency: httpx-kerberos. Tests cover none/simple (no auth object), Basic auth header, Kerberos auth object, missing basic user, invalid auth_type, and tool-layer config propagation.
