Configure DNS service discovery for containers (dnsdock, labels)

[bittner]

As a developer
I want to to access services (aka Docker containers) by their hostnames
So that it's more convenient and intuitive to develop locally,
And it's possible to work on two or more projects in parallel (i.e. no IP address conflict ever).

Acceptance Criteria

• When I run the cookiecutter I can select a "dnsdock" option, and dnsdock is configured in the generated project.
• The generated project README explains how to use the features provided by dnsdock in a (very!) concise way
• There is an easy way to configure and start the dnsdock daemon (and this is mentioned in the README)

• Better Docker Container Management with DNSDock (Medium)
