op-mode: T6175: "renew dhcp interface <name>" does not check for DHCP interface
The current op-mode script simply calls sudo systemctl restart "dhclient@$4.service"
with no additional information about a client interface at all.
This results in useless dhclient processes
root 47812 4.7 0.0 5848 3584 ? Ss 00:30 0:00 /sbin/dhclient -4 -d
root 48121 0.0 0.0 4188 3072 ? S 00:30 0:00 \_ /bin/sh /sbin/dhclient-script
root 48148 50.0 0.2 18776 11264 ? R 00:30 0:00 \_ python3 -
Which also assign client leases to all local interfaces, if we receive one
valid DHCPOFFER
vyos@vyos:~$ show interfaces

Interface IP Address MAC VRF MTU S/L Description
----------- ----------------- ----------------- ------- ----- ----- -------------
eth0 - 00:50:56:bf:c5:6d default 1500 u/u
eth0.10 172.16.33.102/24 00:50:56:bf:c5:6d default 1500 u/u
eth1 172.16.33.131/24 00:50:56:b3:38:c5 default 1500 u/u
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.
