Use github container registry for storing the images and divide the actions in separate files to follow all other apps

[martin-trajanovski]

Description

This PR aims to improve the github actions and spliting them into different files for push to master and pull_request to master. From now on we are using Github container registry for storing the images that we build in the actions.

Motivation

Actions were mixed a bit and DockerHub was used as a storage for images.
