[PATCH v5 1/6] transport-helper: no connection restriction in connect_helper

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

When commit b236752a (Support remote archive from all smart transports, 2009-12-09) added "remote archive" support for "smart transports", it was for transport that supports the ".connect" method. The "connect_helper()" function protected itself from getting called for a transport without the method before calling process_connect_service(), which only worked with the ".connect" method.

Later, commit edc9caf7 (transport-helper: introduce stateless-connect, 2018-03-15) added a way for a transport without the ".connect" method to establish a "stateless" connection in protocol-v2, where process_connect_service() was taught to handle the ".stateless_connect" method, making the old protection too strict. But commit edc9caf7 forgot to adjust this protection accordingly.

Remove the restriction in the "connect_helper()" function and give the function "process_connect_service()" the opportunity to establish a connection using ".connect" or ".stateless_connect" for protocol v2. So we can connect with a stateless-rpc and do something useful. E.g., in a later commit, implements remote archive for a repository over HTTP protocol.
