I have restored maxUserTime.

Sometimes we must hold the connection for a long time. For example, in the
loop retrieve PLC data.

If request timeout the base drive will throw a timeoutException and
cacheManage will close this real connection and set the isConnected of the
leased connection as false.
So we can determine whether the connection is closed in the loop and
automatically connect if it is closed.

If you can merge my New PR. We should remove maxUserTime again.
