Deploy a mock server for time-tracker-api

[enriquezrene]

UI team is working with hard-coded data for now since we don't have an API up and running. Since we have the OPEN API definition file, we can deploy a mock server simulating responses.

A good mock server implementation is prism (https://github.com/stoplightio/prism) which can be installed in a tiny server using the following instructions:

1. Instal prism npm install -g @stoplight/prism-cli
2. Run prim using the Open API specification file prism mock your-swagger-file.json

Acceptance Criteria

• Talk to back-end team in order to have the latest swagger.json file
• Provide the prism output so all team can know what the URLs are
• The URL should be accessible by internet

This is going to have a workaround. We are going to use persistence directly.
