Listen-address in DHCP-server when going VyOS 1.4 to 1.5 will cause problems
Open, NormalPublicBUG

Description

It seems like the migrationscript might needs to get updated regarding DHCP-server when going from VyOS 1.4 to 1.5.

The issue seems to be with set service dhcp-server listen-address 'x.x.x.x' which will make the DHCP-server to fail to behave properly and some configrows will be deleted aswell.

The issue could of course be located elsewhere but triggered by the listen-address config.
