Title: Make setting skipped ports more intuitive

I've wrapped the check for skipped ports with `Array` so that a single port can be set, and called `#to_i` on the ports returned from Docker to make setting them a bit more intuitive.

You can now call `set :rolling_deploy_skip_ports, 5672` to skip a single port.
