Make the hit counter deployable in Docker

[rofrano]

As a Developer
I need the ability to deploy the service in a Docker container
So that I have more deployment options than just Cloud Foundry

Assumptions:

• The alpine:python Docker image should be used as a base
• The shell parameters from the Vagrantfile can be used as a starting point

Acceptance Criteria:

When I issue docker build -t hitcounter .
A proper Docker image should be built
And when I issue docker run -d hitcouner
And I issue docker ps
I should see a hitcounter container running
