ci: create documentation on how to run CI locally for development purposes

[gustavovalverde]

Motivation

Developers might want to run CI tests locally on their machine, so they don't have to wait for the CI if they have faster machines or available cached states locally.

We should create documentation on how to this with Docker and/or a script to automate the whole process when passing environment variables.

Designs

• A Docker documentation or a docker-compose file with the needed steps to run certain tests and rebuild accordingly
• A script to run locally and ensure all the needed dependencies are set and allow to pass arguments to run different tests
