Bug Description
Patch [1] enabled etcd3 by default in devstack. Patch [2] adds the ability to disable etcd3 - this gets s390x devstack working again when the following line is in local.conf
disable_service etcd3
But this is just a circumvention. The root cause is NOT that etcd3 is not working on s390x (it is working!! [5]), but that devstack downloads the (architecture dependent) binaries directly from github.com, e.g. [3]. But etcd does not provide binaries for s390x on github.
Devstack does so, as most distros do not yet have the etcd3.x version available (e.g. with ubutnu 16 it's 2.x).
I opened an issue against etcd to figure out what would need to be done to get that going [4].
Alternatively the following approaches are thinkable:
- Enhance devstack to download the binary and compile it
- Enhance devstack to check whether etcd3 is already installed and use it - otherwise fail for s390x

Allow disabling etcd3
Etcd3 was enabled recently as new service in devstack [1]. But there's
no way to disable etcd3. This is required on architectures where no etcd
binaries are available (e.g. s390x). The long term goal of course should
be to have those binaries available. The short term circumvention is to
allow disabling the service in local.conf:

Add etcd3 support for s390x
Since [1] devstack is failing on s390x with "Distro not supported".
The reason for this is the missing etcd3 support. It worked before
[1] as we were able to disable etcd3 via local.conf. But as etcd3 is
a base service, we might not be able to rely on this workarond in
the future anymore.
As there is no etcd3 binary hosted on github like it is for other
architectures, the user needs to specify an alternative download
URL via local.conf. Otherwise devstack will exit with an appropriate
error message.
