[SURE-9997][RFE] Pass secrets and config maps to workload cluster

[alexander-demicev]

Is your feature request related to a problem?

We're using HelmApp to install out-of-tree cloud providers across multiple clusters, as shown in this example. For our use case, we need to pass a ConfigMap and a Secret to all workload clusters where HelmApp installs the chart.

Ideally, we'd like to have something similar to how one of Cluster API CRDs handle this, like in this template:

resources:
  - kind: Secret
    name: vsphere-config-secret
  - kind: Secret
    name: cloud-provider-vsphere-credentials
  - kind: ConfigMap
    name: cpi-configmap
