Duplicate Secret Created
When enabling Ambient by setting the following in values:
```
istio:
ambient:
enabled: true
```
The following error is received:
{width=381 height=67}
This is likely due to the logic for the imagePullSecret creation for metrics-server which now gets enabled/disable automatically (previously it was always disabled in our test-values).
Currently, the logic only takes into account whether or not the istioCNI is enabled and may simply need to be expanded to also include logic for when ambient is enabled:
