T6874: [QoS] Add class filter by ether

Implement a command to configure QoS policy filters by ether properties.
The supported match types include:
- Destination: Specify the Ethernet destination address.
- Protocol: Define the Ethernet protocol.
- Source: Set the Ethernet source address.

`set qos policy <type> <name> class <id> match <match-id> ether <destination|protocol|source> <val>`
