Feature/fix local docker setup

[samdavidge]

I have made a series of small changes which ensures that the microservices build and register with the Control Tower locally with Docker.

The changes to this repo are:

• Change README to be consistent with other repos
• Fix port typo to ensure it is using 5001

Hey @ethanroday this is a local/test key that is used (and committed) across many of the repos.
