[ISSUE #7042] TlsTest's serverRejectsSSLClient test case will throw TooLongFrameException

…tsSSLClient test case will throw TooLongFrameException

Which Issue(s) This PR Fixes

Fixes #7042

Brief Description

In the disabled TLS mode Server, it will not reject the request directly and then request contain SSL cert will cause TooLongFrameException in the NettyDecoder.

more detail see #7042

How Did You Test This Change?

To conform to the semantics of the disable mode, I test the change in two case:

1. when server in disabled mode, then client send ssl request to server. and then server will reject the request.
2. when server in disabled mode, then client send no auth request to server. and then server will accept the request.
