No imagePullPolicy for self signed SSL certificate container

Describe your problem

The chart does not have a configurable value for imagePullPolicy in the alpine/openssl initContainer. This causes the imagePullPolicy to be set to Always by default resulting in excessive pulling from Docker.

Describe your ideal solution

As a user of the Helm Chart, I want to be able to configure the imagePullPolicy for the self signed certificate generation.

Version

7.6.1

App version

v2.46.0

Additional Context

Why not consider using Helm's built-in [genSelfSignedCert](https://helm.sh/docs/chart_template_guide/function_list/#genselfsignedcert) function? This eliminates the need for the initContainer all together
