Etcd doc hard coded for amd64

[John Studarus]

The Etcd Ubuntu documentation hard codes in the amd64 architecture. For ARM machines, this needs to be changed from:

etcd-${ETCD_VER}-linux-amd64.tar.gz
etcd-${ETCD_VER}-linux-arm64.tar.gz

There needs to be a little more intelligence in the script or a warning in the documentation to select the correct architecture.

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [X] This doc is inaccurate in this way: ______
- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.

If you have a troubleshooting or support issue, use the following resources:

ARCH=`dpkg --print-architecture`
curl -L https://github.com/coreos/etcd/releases/download/${ETCD_VER}/etcd-${ETCD_VER}-linux-${ARCH}.tar.gz -o /tmp/etcd-${ETCD_VER}-linux-${ARCH}.tar.gz
tar xzvf /tmp/etcd-${ETCD_VER}-linux-${ARCH}.tar.gz -C /tmp/etcd --strip-components=1

Also, this environment variable needs to be set in the etcd config file.
[Service]
Environment="ETCD_UNSUPPORTED_ARCH=arm64"
LimitNOFILE=65536

Maybe needs to change for all distros in https://docs.openstack.org/install-guide/environment-etcd.html or mentions that the install-guide is mainly based on amd64 architecture.

The current version of the page doesn't seem to have this issue.

[John Studarus (g-john-j)]

The issue is now on this page:

Thanks John; I missed that.
