Include the DHCP option names in the hash calculations
In #977 (closed), we decided to calculate the DHCP option hash excluding its name, because the lookup for custom DHCP options is not implemented. It causes the DHCP option name to be unknown in several use cases, so we don't acquire an expected hash.
The support for the custom DHCP option will be added in #954. After merging it, we should include the DHCP option in the hash calculations and remove the temporary workaround.
