Allow `perfdhcp` to behave like an endpoint client

name: perfdhcp DHCPv4 not as a relay
about: Support for perfdchp DHCPv4 Operation as a normal client (not relay)

Is your feature request related to a problem? Please describe.

I would like to be able to use perfdhcp to test a dhcp implementation including the ability to process DORA over broadcast.

Describe the solution you'd like

An option that enabled perfdhcp to act as an end client as opposed to a relay, which means using broadcast traffic, not setting giaddr and binding to port 68 and not 67.

Additional context

I'm specifically trying to tests a DHCP application on the same host. This means that the dhcp process binds on 67 and the current behaviour of perfdhcp is to also bind on 67 which fails. If perfdhcp can function as a normal client, it can use 68.
