BUG/MINOR: ssl: fix warnings about methods for opensslv1.1.

This patch replaces the calls to TLSvX_X_client/server/_method
by the new TLS_client/server_method and it uses the new functions
SSL_set_min_proto_version and SSL_set_max_proto_version, setting them
at the wanted protocol version using 'force-' statements.
