with the upgrade to etcd/v3 by default, `flannel` tests are failing because it does not support etcd/v3 at the moment. we pin the `etcdctl` version to `V2` and run `etcd-member` with `v2` support. Signed-off-by: Mathieu Tortuyaux <mathieu@kinvolk.io>
with the upgrade to etcd/v3, locksmith still relies on etcd/v2. While `locksmith` is being upgraded, we enable the `etcd` v2 support. Signed-off-by: Mathieu Tortuyaux <mathieu@kinvolk.io>
since we are testing v2 backup, we need to enable v2 support in case we are running etcd v3. Signed-off-by: Mathieu Tortuyaux <mathieu@kinvolk.io>

Maybe limit it to just one env var?

if we don't provide the `--preserve-env` flag, we do not preserve the environment variable `ETCDCTL_API` in sudo mode. `backup` is ran against `etcdctl` v3 which does not know this command. Signed-off-by: Mathieu Tortuyaux <mathieu@kinvolk.io>
