Feature Request: add ability to specify "table" for the netbird interface to support more advanced routing

[finnje]

In wireguard you can specify a network table for the interface. This allows you to do policy based routing for more advanced use cases.

Along with the ability to specify a table the routing functionality in the UI would need to be updated to allow the ability to specify ip rules and routes to be added to the new route table. More than likely an "fwmark" would need to be applied to packets as well.
