Describe the feature request

An EnvoyFilter with an insert position relative to another filter (e.g., INSERT_BEFORE) can be
fragile because the default order of filter evaluation is based on the creation time of the filters.
If the insertion point for a filter is not found, the filter will not be added to the chain and nothing will
appear in the error log to indicate that it was skipped.

Documentation describing this subtlety has been added in istio/istio.io#10935.
It would be good to also make istioctl analyze produce a warning message for this kind of
fragile configuration.
