/// @brief Configures DHCPv6 server
///
/// This function is called every time a new configuration is received. The
/// extra parameter is a reference to DHCPv6 server component. It is currently
/// not used and CfgMgr::instance() is accessed instead.
///
/// Test-only mode is supported. If check_only flag is set to true, the
/// configuration is parsed, but the actual change is not applied. The goal is
/// to have the ability to test configuration.
///
/// This method does not throw. It catches all exceptions and returns them as
/// reconfiguration statuses. It may return the following response codes:
/// 0 - configuration successful
/// 1 - malformed configuration (parsing failed)
/// 2 - commit failed (parsing was successful, but the values could not be
/// stored in the configuration).
///
/// @param server DHCPv6 server object.
/// @param config_set a new configuration for DHCPv6 server.
/// @param check_only whether this configuration is for testing only
/// @return answer that contains result of the reconfiguration.
/// @throw Dhcp6ConfigError if trying to create a parser for NULL config.
