Euan Kemp e10e068084 dev-db/etcd: add etcdctl useflag
This paves the way to including the etcdctl binary from another package.

See https://github.com/coreos/bugs/issues/1717 for some context around
this.

As discussed on that issue, a long term solution here might be torcx.

However, I don't think we need to actually wait for torcx to do this
since the etcd3 cli is meant to be perfectly backwards compatible.

This will also allow our docs around using `etcd-member.service` to be
more readable/usable, since right now the docs don't have an easy way to
talk to the etcd cluster from a Contaienr Linux machine.
