MEDIUM: ssl: ssl_methods implementation is reworked and factored for min/max tlsxx
Plan is to add min-tlsxx max-tlsxx configuration, more consistent than no-tlsxx.
This patch introduce internal min/max and replace force-tlsxx implementation.
SSL method configuration is store in 'struct tls_version_filter'.
SSL method configuration to openssl setting is abstract in 'methodVersions' table.
With openssl < 1.1.0, SSL_CTX_set_ssl_version is used for force (min == max).
With openssl >= 1.1.0, SSL_CTX_set_min/max_proto_version is used.
