ot::MeshCoP::SecureTransport::SetMaxConnectionAttempts() method

Sets the maximum number of allowed connection requests before socket is automatically closed. This method can be called when socket is closed. Otherwise `kErrorInvalidSatet` is returned. If @p aMaxAttempts is zero, no limit is applied and connections are allowed until the socket is closed. This is the default behavior if `SetMaxConnectionAttempts()` is not called.
