Enhance Helm Collector to include helm values

[avaakash]

Describe the rationale for the suggested feature.
The current helm collector collects the revision history with status, a good addition will be to add the functionality to collect helm values for each of those releases. Helm values provide an overview of what configuration values were provided by the user and in larger deployments, they can act as a first area to look at to know about the configuration details of the user's deployment.

Describe the feature
We can add a toggle for the user if they want to collect helm values or not, if they want to, we fetch the helm values for each of the revisions of the release.
We can easily implement this in the current implementation of the Helm collector.

Describe alternatives you've considered
I haven't considered any other solutions

Additional context
This change will not require any big changes, we can do a simple plug-in to the already present Helm collector to achieve this.
