Make possible to declare cronTabs inside docker-compose file.
⇒ Also, add multiple compose file injection with `-c` arguments
⇒ Also, fixes “ignore depends on” for same pod
⇒ Also fixes
* fix [Be able to specify compose.yml files and its override #21](https://github.com/metal3d/katenary/issues/21)
* fix [Be able to ignore ports to expose in a katenary.io/ports list #16](https://github.com/metal3d/katenary/issues/16)
And more fixes… (later, we will use branches in a better way, that was a hard, long fix process)
