Handle receiving a request whose path is '*'.
RFC 7231 defines an OPTIONS * request as being something that a client
can send as a low-effort way to probe server capabilities or readiness.
Rather than bother the user with this, we simply fast-path it back to
an empty 200 OK. Any non-OPTIONS verb gets a 405 Method Not Allowed
telling the client they can only use OPTIONS.
