ps command for rabbitmqctl wait

[alterationx10]

I believe the default ps that comes with alpine is a BusyBox command. rabbitmqctl wait seems to use ps, but doesn't properly wait with it. I get something like:

Waiting for rabbit@54e9f3ce2ca9
pid is 6
Error: process_not_running

Adding in RUN apk --no-cache add procps in my Dockerfile seems to fix the issue. Perhaps it would be good to add this into the main image atrabbitmq/3.6/alpine/Dockerfile?

That sounds reasonable to me. 👍
