This PR extends
SnowflakeHook's OAuth implementation, allowing users to specify atoken_endpointextras parameter to support external IDPs (other than Snowflake's built-in).It also introduces the
grant_typeparameter in order to support grant types other thanrefresh_token. This initial implementation provides support for theclient_credentialsgrant type, which can be provided through the login/password fields to acquire an access token.Backwards compatibility with the existing interface is preserved.
