Upgrade etcd to 3.3.17 (#3343)

I originally intended to upgrade etcd to 3.4.2, but at this time,
the module is broken, and cannot be included, under the original
import path, or the new go.etcd.io import path.

See etcd-io/etcd#11154 for more info.

Closes #3278

Signed-off-by: Eric Chlebek <eric@sensu.io>

* Re-write tracing middleware tests to use prometheus_client/testutil (#3342)

The testutil package was introduced in v0.9 and exposes some helpers for
for writing simple unit tests.
