Provide JDK SSLContext/Netty OpenSSLContext bridge and allow using OpenSSL

In order to use OpenSSL with Netty (which is much faster than JDK implementation), and stick with WildFly SSL initialization, we need to provide a bridge from JDK SSLContext into OpenSSLContext.

The next step is to use this bridge here: https://github.com/infinispan/infinispan/blob/fd3061a684c13aa7c22d215f43910735bf7ff4a6/server/router/src/main/java/org/infinispan/server/router/router/impl/hotrod/handlers/util/SslUtils.java#L35

Finally, we need to put netty-tcnative into the server's classpath.
