This change will let the developer know the configuration of the server socket when the errors happen through debugging enabled.

1. Updated the code format, the case of log messages
2. New boolean variable CSFound is removed by combining the error messages together
3. Only enabled cipher suites of server socket will be printed out
4. Still keep the list of the legacy suites since it is created during the process. It will only be printed out when it is available.
