etcd-server and etcd-client to stretch-backports

[Stefan Eriksson <stefan@eriksson.cn>]

Hi

It would be really nice if the packages etcd-server and etcd-client 
could get added to stretch-backports (from buster), the packages doesnt 
exist on stretch today and it would be nice to be able to use apt 
instead of manually install the binary and systemd service file etc.


Best regards.

Stefan
