op-mode: T6175: "renew dhcp interface <name>" does not check for DHCP interface
The current op-mode script simply calls sudo systemctl restart "dhclient@$4.service"
with no additional information about a client interface at all.
This results in useless dhclient processes

Which also assign client leases to all local interfaces, if we receive one

172.16.33.102/24 and 172.16.33.131/24 are stray DHCP addresses.
This commit moved the renew command to the DHCP op-mode script to properly
validate if the interface we request a renew for, has actually a dhcp address
configured. In additional this exposes the renew feature to the API.
