Problem was in Galera library where wsrep_provider socket.ssl_cipher
parameter was defined as type_bool when it should have been string
type.
Therefore, this test requires Galera library version 26.4.21 where
fix is. Here we just verify that we can upgrade ssl parameters
so that socket.cipher = AES256-SHA and we use OpenSSL.
