Fix layer2 not arping when IP changes

[KnicKnic]

Fixed #471

I noticed that SetBalancer in Announcer.go essentially short circuits if the load balancer is already set. I also saw that it was cached in main.go of the speaker for the service.

So to fix this, I just deleted the existing balancer for the service and allowed it to fall through and create a new one with the new IP.

Hi @KnicKnic,
This looks like a good change. I will try and give it a better lookover tonight. In the meantime, could you squash the merge commit and rebase your changes onto master?
Also, while I know this a small change, could you include some of the description you have in your PR in your commit message?

@daxmc99
Do you mean to rebase on main or master. I rebased of main and force pushed (as master conflicts with main). Btw main/master is confusing :-) .

I am seeing the rebase and merge option available again in the GitHub UI so what you did worked 👍

Thanks @KnicKnic for being patient with the slow turnaround, and thanks @daxmc99 for reviewing!
