change of etcd.image.registry triggers ERROR

[mkyc]

If you change value etcd.image.registry (into ie.: local proxy) you'll get following error:

Error: execution error at (apisix/charts/etcd/templates/NOTES.txt:124:4): 

⚠ ERROR: Original containers have been substituted for unrecognized ones. Deploying this chart with non-standard containers is likely to cause degraded security and performance, broken chart features, and missing environment variables.

Unrecognized images:
  - <my local proxy here>/bitnamilegacy/etcd:latest

If you are sure you want to proceed with non-standard containers, you can skip container image verification by setting the global parameter 'global.security.allowInsecureImages' to true.
Further information can be obtained at https://github.com/bitnami/charts/issues/30850

and setting:

global:
  security:
    allowInsecureImages: true

fixes it, but I'm not sure that this is expected behavior.
