Issue details

As discussed in this issue in the official Helm repository it is sometimes necessary to supply files for a packaged chart, e.g. each customer of a company needs to supply their own p12 cert file.

While it is possible to write the base64 encoded string into the values, it would make the k8s.helm.v3.Release object more readable if we could make use of the --set-file flag to supply files, which are external to the chart.

Along these lines would be the ability to use a Pulumi Asset as a chart "value" to get the asset's content.
