Unrecognized option "firewall_name" under "hwi_oauth"

After upgrade of my project to symfony 2.8 I get the following error when I push the code to staging server.

[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException] Unrecognized option "firewall_name" under "hwi_oauth" When i remove firewall_name option then I get an error that the option is required.

If someone provide some insight will be much appreciated.
