While doing that we found that we needed to refactor the fakes to handle
command line arguments which are not known up front; we do this by using
regular expresseions.
- Start() should only return when the process is actually up and
listening
- It may take some time to tear down a process, so we increased the
timeout for Stop() (to some random number)
- We make sure Std{Out,Err} is properly initialized, we should not rely
on Ginkgo/Gomega to do that for us
To start an apiserver:
```
apiServer := APIServer{Path: "/path/to/my/apiserver/binary"}
session, err := apiServer.Start("tcp://whereever.is.my.etcd:port")
Expect(err).NotTo(HaveOccurred())
```
When you're done testing against that apiserver:
```
session.Terminate().Wait()
```
...or if you prefer:
```
gexec.Terminate()
```
...which will terminate not only this apiserver, but also all other
command sessions you started in this test.
