Close all resources if doStart fails

[s1monw]

if we for instance can't bind a port we fail to stop the client bootstrap etc. To prevent this we can just call doStop() it has all the relevant checks in place.

we had a thread leaks reported on CI due to that http://build-us-00.elasticsearch.org/job/es_g1gc_master_metal/3929/

@spinscale can you take a look

[spinscale]

LGTM, thinking if we should generalize this a bit more and have all AbstractLifeCycleComponents execute something like this to clean up

[s1monw]

@spinscale I agreee but in general I think we should remove #stop completely, what do you think?

[spinscale]

@s1monw agreed, we still have close() due to Releasable then

[s1monw]

I'd love to also remove #start if possible 👯

hm. Wondering, how should that work with keeping in mind that constructors in guice apps should not throw exceptions and stuff (all done via listeners?)? I'd be fine with one method for stopping/starting each
