Avoid container leaks by setting hook before container creation

[bsideup]

Hi!

If somebody will stop execution during the container creation, especially during the "waitUntilContainerStarted" phase, hook will not be executed, seems like finally doesn't work in case of the SIGTERM.

Symptoms: I see a lot of non-destroyed containers after test execution when we stop our Jenkins job.

This fix will add a hook just before container is being created to make sure that it will be executed afterwards.

Thanks!

hey @rnorth,

Could you please take a look at this one for the next release as well? I wouldn't call it critical, but definitely annoying and causing a lot of issues on CI servers and local environments.

Thanks!

Hi,
Sure - this is an important one to fix so I'll try and merge and release
quickly. If you don't mind, I'll prioritise inclusion of this in 1.0.3 over
#106, and perhaps hold that back for the next point release. I hope this is
OK!
Cheers
Rich

@rnorth makes sense :)

BTW CircleCI failed for some reason, can't pull MySQL image. Re-run maybe?

@bsideup that's annoying - re-running!

Looks good to me, so merged.
