Add Automatic Upcloud DNS firewall rules

[nicovs]

Is your feature request related to a problem? Please describe. I need to add the 8 DNS Rules by hand over the CLI. Not that this is a major problem, but it would be nice to be able to invoke 1 single CLI command

Describe the solution you'd like n upctl CLI option to the create, delete, show option like:

upctl server firewall add-automatic "${SERVERNAME}" 

Describe alternatives you've considered

upctl server firewall create "${SERVERNAME}" --direction in --action accept --position 1 --family IPv4 --protocol udp --source-port-start 53 --source-port-end 53 --src-ipaddress-block 94.237.40.9/32 --comment "Upcloud DNS"
upctl server firewall create "${SERVERNAME}" --direction in --action accept --position 1 --family IPv4 --protocol tcp --source-port-start 53 --source-port-end 53 --src-ipaddress-block 94.237.40.9/32 --comment "Upcloud DNS"
upctl server firewall create "${SERVERNAME}" --direction in --action accept --position 1 --family IPv4 --protocol udp --source-port-start 53 --source-port-end 53 --src-ipaddress-block 94.237.127.9/32 --comment "Upcloud DNS"
