Dear, Developers
I need dhcp lease clear feature.
After enable this
```
set service dhcp-server hostfile-update
```
I can find hostname of linux servers with hosts file. But when i try to rename the hostname. Where i can clean dhcp lease immediatly?
I found that edgeos has the command `clear dhcp lease ip 172.16.3.20` to force delete the lease. Can we implement in vyos ? This is immport for me.
