Should MutatingWebhook failurePolicy be Ignore?

[ca-scribner]

/kind feature

Describe the solution you'd like
Not sure if this is a bug or a feature request, but the MutatingWebhook failurePolicys are set to Ignore, which means it is easy to not notice if your webhook calls are failing. This was noticed when debugging #1795.

Is this the best configuration? Are there cases where having the Experiment and Pod mutations fail can still lead to viable setups? If there are not, maybe failurePolicy: Fail would be better so configuration errors are easier to find.
