include hot reloading dockerfile

[xenoterracide]

in the event you want your service to reload on source code changes for local "cluster" development. it would be nice to have an optimized example image of this.

e.g. instructions similar to https://medium.com/@lhartikk/development-environment-in-spring-boot-with-docker-734ad6c50b34

Thanks for the link. I'm not convinced that running in a container at dev time is such a great idea, so unless a lot of other people disagree I don't see a compelling case for making this change. Interesting article though.
