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)
Use compose-go https://github.com/compose-spec/compose-go to make Katenary parsing compose file the official way.
Add labels:
- `volume-from` (with `same-pod`) to avoid volume repetition
- `ignore` to ignore a service
- `mapenv` (replaces the `env-to-service`) to map environment to helm variable (as a template string)
- `secret-vars` declares variables as secret values
More:
- Now, environment (as secret vars) are set in values.yaml
- Ingress has got annotations in values.yaml
- Probes (liveness probe) are improved
- fixed code to optimize
- many others fixes about path, bad volume check, refactorisation, tests...
- Added a message to explain to the user that it needs to build and push
images
- The Release Name string is now a constant ins source code, later we will be able to
change it to (for example) a template call
- SHA256 injected label (from docker-compose file content) is a bit long, SHA1 is shorter
- We now add compose command line and generation date in the Values file
- Code cleanup, refactorisation and enhancements
- More documentation in the source code
