Description

`make test` is a dependency of `make docker-build` which is used frequently when doing local development. A kube-apiserver and a etcd process are left behind each time. After a number of runs, `make test` starts failing with cryptic errors. The error goes away if the leaked processes are killed manually.

Steps to reproduce

1. clone https://github.com/openshift/sandboxed-containers-operator.git
2. pkill -e 'etcd|kube-apiserver'
3. run make test

Expected result

No matter if the test succeed or fails :

$ pgrep 'etcd|kube-apiserver'
$ 

Actual result

$ pgrep 'etcd|kube-apiserver'
86592
86615
$

Impact

DoS for anyone or anything heavily relying on `make test`
