weave-gitops HelmCharts with GitOps Run

As a user, I want to pull down someone's latest pull request and run gitops run against the helm charts on that branch.

I expect my values to be copied over from an existing helm release if one exists.
I should be able to run gitops run against the same resource without conflicts.
As a user, I expect gitops run to clean up any resources I've created when I turn it off, even if those resources are no longer referenced by the manifests.

As a user, I want to pull down someone's latest pull request and run gitops run against a kustomization overlay on that branch.

I already have a kustomization overlay running on a cluster and I expect to be able to run against that same overlay with gitops run.
I should be able to run gitops run against the same resource without conflicts.
I don't want gitops run to be smart about whether the cluster is bootstrapped or not. I just want to run gitops run knowing I have done all of that.

Helm

As a user, I want to be able to leverage the existing values that are set on a helm release if one is already running.
As a user, I expect to be able to leverage the existing secrets that are be used by the existing workload.
As a user, when I run against a helm chart and there is no helm release then I expect gitops run to create a helm release object on my behalf.
As a user, if I wanted to customize the helm release values I can and those would take precedence over the original helm release values.
When I run against a helm chart I would expect a temporary HelmRelease to be created and not a Kustomization.
