Create Docker image

[albamig]

• Create a Docker image to run the microservice.

• Provide a docker-compose file to get the dependencies up.

  • Create database structure within postgres container

• The Docker image must be small in size.

This issue will partly be solved in the new repository Clariteia/minos_dockerimage#1.

There, the base image will be provided and here we will just cover the microservice template image.
