when there is new version for one chart, which supports batch upgrade applications deployed using this chart

Summary
When there is new version for one chart, which supports batch upgrade applications deployed using this chart.Better support select part and select all.

Background and rationale
We have deployed hundreds of applications with one chart.When the chart template update,we hope the applications can follow the changes from the chart.For the moment,the only way to upgrade applications by kubeapps is upgrading applications one by one.It would be nice if batch upgrades were supported.List all apps deployed using this chart first, filtered by labels or select all with one click.

Interesting @cwyj , thanks. Other packaging systems, such as Carvel (rather than Helm), do have the option to support auto-upgrade (that is, when you specify your installed package, you do so with a semver, so you can specify it such that any newer minor version will match and be installed automatically). Helm is procedural (you tell it to install a specific version, rather than declare a target state), so doesn't support this, but right, Kubeapps could include some UX feature that allows selecting a bunch of installations... worth thinking about.
