Not possible to set imagePullSecrets for sidecars

[gtirloni]

Report

While using a private container registry with authentication, I noticed that it's not possible to specify imagePullSecrets in the pxc CRD for sidecars (e.g. mysqld-exporter).

More about the problem

Sidecars fail to pull image from private repository.

Steps to reproduce

pxc:
  sidecars:
    - name: mysqld-exporter
      image: some.private.registry/mysqld-exporter
      imagePullSecrets:
        - name: secret_name

Versions

1. Kubernetes: 1.28
2. Operator: 1.14
3. Database: MySQL 8.0.32-24.2

Anything else?

Hi @gtirloni we have a PR percona/percona-server-mysql-operator#921 to fix it. It will be fixed in v0.11.0.
JIRA task is: https://perconadev.atlassian.net/browse/K8SPS-414

@gtirloni, you can use imagePullSecrets under the PXC section for these needs. As you know, we can set imagePullSecrets on the pod level only. So, it will work for your custom sidecar.
