etcd systemd configuration missing

[chuckn246]

I made it to 07-bootstrapping-etcd and noticed the systemd service configuration is missing.

I looked at the git history and noticed that the heredoc that originally created the service file was recently removed.

I was able to get the service started by using the etcd systemd service example from here: https://github.com/etcd-io/etcd/blob/main/contrib/systemd/etcd.service then editing it with code from the commit where the code was removed.

etcd_name=$(hostname -s)
internal_ip=$(hostname -I | awk '{ print $1 }')

I'm not sure if this is correct yet but the service starts.

In the doc, it prompts you to use the the etcd service found in the units/ dir
