Integrate a modern linting tool

[LaimeJesus]

Currently, we are using an older version of tslint which is already deprecated.
We would like to use eslint as an alternative with a react and typescript plugin.
These are some examples:

• https://github.com/typescript-eslint/typescript-eslint
• https://github.com/iamturns/eslint-config-airbnb-typescript

The select packages should be added as dev-dependencies and a new npm command to run the linting.
