Fixes #3682

Existing helm.sh/hook-delete-policy annotation variables (hook-failed, hook-succeeded) do not allow to leave failed jobs for debugging without blocking the next job launching: every failed job must be deleted manually before the next related release is launching (installing, updating or rolling back).

New policy, before-hook-creation, removes the hook from previous release if there is one before the new hook is launched and can be used with another variable.

Adding --set-string flag to force string values.
