title: 2 Helm Charts with shared Redis dependency
body: <p>Currently, I have 2 Helm Charts - Chart A, and Chart B. Both Chart A and Chart B have the same dependency on a Redis instance, as defined in the <code>Chart.yaml</code> file:</p>
  
  <pre><code>dependencies:
  - name: redis
    version: 1.1.21
    repository: https://kubernetes-charts.storage.googleapis.com/
  </code></pre>
  
  <p>I have also overwritten Redis's name since applying the 2 Charts consecutively results in 2 Redis instances, as such:</p>
  
  <pre><code>redis:
    fullnameOverride: "redis"
  </code></pre>
  
  <p>When I try to install Chart A and then Chart B I get the following error:</p>
  
  <p><code>Error: rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: kind: PersistentVolumeClaim, namespace: default, name: redis</code></p>
  
  <p>I was left with the impression that 2 charts with identical dependencies would use the same instance if it's already present?</p>
