Function connect

pub(crate) async fn connect<R: Runtime>(
    connector: &HsClientConnector<R>,
    netdir: Arc<NetDir>,
    config: Arc<Config>,
    hsid: HsId,
    data: &mut Data,
    secret_keys: HsClientSecretKeys,
) -> Result<Arc<ClientCirc>, ConnError>

Actually make a HS connection, updating our recorded state as necessary

connector is provided only for obtaining the runtime and netdir (and mock_for_state). Obviously, connect is not supposed to go looking in services.

This function handles all necessary retrying of fallible operations, (and, therefore, must also limit the total work done for a particular call).

This function has a minimum of functionality, since it is the boundary between “mock connection, used for testing state.rs” and “mock circuit and netdir, used for testing connect.rs”, so it is not, itself, unit-testable.
