Add option to skip schema-validation for values in HelmChartInflationGenerator

Eschewed features

• This issue is not requesting templating, unstuctured edits, build-time side-effects from args or env vars, or any other eschewed feature.

What would you like to have added?

Add a field skipSchemaValidation to the HelmChartInflationGenerator and pass it as --skip-schema-validation to helm if it's value is true

Why is this needed?

helm enforces schema validation for the values passed to a chart if the chart defines a schema for the expected values. While this feature might be practical in some use-cases it is a problem when using a helm-chart as dependency when the passed values contain properties for other dependencies or the main chart.

Thus helm added the option --skip-schema-validation (helm/helm#11510). Unfortunatly there seems to be no way to pass this flag using the HelmChartInflationGenerator

Can you accomplish the motivating task without this feature, and if so, how?

As there seems to be no way to disable helm's schema-validation globally, i see no (good/easy) way to use such charts with the HelmChartInflationGenerator otherwise.

What other solutions have you considered?

n/a

Anything else we should know?

No response
