Summary

Each Service Operator runs its own webhook, but those webhooks are also imported and run under the {{{}openstack-operator. This unnecessary duplication of webhook implementation results in wasted CPU cycles and additional cluster load. }}

Proposal

We can disable webhooks at the service level by setting ENABLE_WEBHOOKS=false in the Dockerfile. However, when running CI in Prow for things like Kuttl, we will need to build a bundle that has ENABLE_WEBHOOKS=true.

Steps:

1. Update the Prow CI jobs script to ensure the BuildConfig passes the ENABLE_WEBHOOK=true environment variable
2. Add the ARG ENABLE_WEBHOOKS to each Dockerfile with a default of false.
3. Set the ENV variable in each Dockerfile to ensure this ARG is used

openstack-operator should leave this default set to true.
