HelmRelease.spec.persistentClient

PersistentClient tells the controller to use a persistent Kubernetes client for this release. When enabled, the client will be reused for the duration of the reconciliation, instead of being created and destroyed for each (step of a) Helm action. This can improve performance, but may cause issues with some Helm charts that for example do create Custom Resource Definitions during installation outside Helm's CRD lifecycle hooks, which are then not observed to be available by e.g. post-install hooks. If not set, it defaults to true.
