[cetic/fadi] Use Helmfile instead of the umbrella Chart?

[alexnuttinck]

Is your feature request related to a problem? Please describe.

The current fadi Helm is hard to maintain and this repository is not coupled with fadi documentation.

Describe the solution you'd like

Replace this Helm chart by using Helmfile.
Benefits of using helmfile:

• add the helmfile in the fadi repository and deprecate this repository.
• helmfile adds a lot of interesting features:
  • a single file to rule all the Helm charts.
  • the presence of dag/hooks: for instance, we can launch ldap first and be sure that it is ready before launching other services.
  • you can create namespaces through the helmfile.
  • you can have multi-environment values. (setup fadi with the needed tools depending of the environment).
  • some other advantages (the diff module for instance, as it is declarative).
• ...

The discussion is now open 😄

any idea of the effort required to do this?

@banzo 1/2 days to migrate the Helm chart to helmfile, update the docs and make some tests :-).

But it would require more efforts if we want to implement some hooks, environments and other features provided by helmfile.
