gateway_announcement.sh depended on removed dhcpd

[AiyionPrime]

dhcpd was the service file of the isc server, which was removed before kea was rolled out.

The new kea role should have added its own service, which either is just called differently or has not been roled out on sn09 and sn07 for some reason.

This became only clear, after sn09 was deployed tonight, as on sn07 the crontab has been altered in joyful expectation of #124.

This is linked to #113.

I just looked for references, where it works,
SN01 is not a good example:

On sn08 and sn10 the ISC server is still running.

[AiyionPrime]

The new kea dhcp role indeed does setup a service which is called differently than dhcpd as of f918f18.

I hotfixed this on sn07 and sn09 but the next roleout of master of us will break things again.
(lemoer codefetch please see this)

This is rather urgent, please reconsider the service name, or give good reason why to keep calling it differently than dhcpd.

It's nice that on of our scripts depended on this, I have no clue what else expects the dhcpd service to be called dhcpd.

I just added the hotfix to master; in case you decide on changing the service name back to dhcpd the commit to revert is 6c58512

Feel free to close once you decided on how to name the service, @1977er :)

Sorry for the trouble. I wasn't aware of that dep in gateway_announcement. I want to go with the name chosen by Debian. I shouldn't have pushed this to master without a PR.

[AiyionPrime]

No worries.
