As explained in #102, the compose-go package changes types and needs
massive changes.
This branches is OK for now, but needs some tests.
It MUST be quickly fixed to be integrated in main branch.
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)
