Minimize configuration by placing task definitions in the same configuration

[robmoorman]

As #6 purposed, it can be an option to complete get rid of the separate task definitions files.
Having all configuration in one place and in YAML is maybe a better option for better maintainability.

This makes it indeed a lot simpler, although you will need #6 for this otherwise there is a lot of code-duplication between various envs
