Possibility to add additional labels on all helm chart resources

[bastienbosser]

What new functionality do you want?

Add a commonLabels variable in the values.yml file that allows to add additional labels on all helm chart resources.

How would the end user gain value from having this feature?

As you know, labels can be used to organize and to select subsets of objects. In my case of use it allows me to group the applications by category and to check by a simple command the status of it.

As examples, for all security applications, I put a label "my-cluster-name/application_group: security". Then I just have to make the command "kubectl get all -A -l my-cluster-name/application_group=security" to know the status of all applications that provide security.

Add a list of criteria that should be met for this feature to be useful

I don't really know what you expect in this field
