-It is possible to define a list of `ConfigMap` and `Secret` resources
-from which to take values. The values are merged in the order given,

-lower priority than the values inlined in the `HelmRelease` via the
-`spec.values` parameter.

-    valuesKey: crt
-    targetPath: tls.crt

-
-The definition of the listed keys is as follows:
-
-- `kind`: Kind of the values referent (`ConfigMap` or `Secret`).
-- `name`: Name of the values referent, in the same namespace as the
-  `HelmRelease`.
-- `valuesKey` _(Optional)_: The data key where the values.yaml or a
-   specific value can be found. Defaults to `values.yaml` when omitted.
-- `targetPath` _(Optional)_: The YAML dot notation path at which the
-   value should be merged. When set, the `valuesKey` is expected to be
-   a single flat value. Defaults to `None` when omitted, which results
-   in the values getting merged at the root.
