Matthew Jaffee 555d185929 add wrapping to differentiate etcd errors
we had a CI job fail in an interesting way, but can't tell if the
etcd retrying stuff is working, so adding in this wrapping so we can
better differentiate the errors if we see it again.

Job is here: https://gitlab.com/molecula/featurebase/-/jobs/1977060827

Failure is:

```
=== RUN   TestClusterStuff
    cluster_test.go:36: creating index: against http://pilosa2:10101/index/testidx 404 Not Found: 'creating index: sending CreateIndex message: executing request: against http://pilosa3:10101/internal/cluster/message 500 Internal Server Error: 'processing message: getting index: testidx: etcdserver: request timed out
        ''
