FR : Hidden Profile Fields as Hints

[fcomte]

Any field in the user profile can be greyed out. When a field is greyed out, it is not automatically injected into the Helm chart launcher, but it can still be used as a suggestion or hint during configuration.

• add a way to greyed out fields in the user profile. We should allow greyed out item of arrays (maybe for any objects but not sure).
• add hints on helm chart for this fields. Hints must be coherent for item of arrays ( maybe for any objects ).
