Add possible configure image pull secret

[ByJacob]

Adding the imagePullSecrets configuration option is an important step in your project. Why it's important.

🔐 Security: imagePullSecrets allow secure and authorized retrieval of container images from private Docker Hub repositories or other container registries. This means we can control access to images, which is crucial in production.

🏢 Private Repositories: In some cases, especially in larger organizations, container images are stored in private repositories where access is restricted. Configuring imagePullSecrets allows for authentication and authorization, which is necessary to retrieve these images.

🔐 Separation of Privileges: The ability to configure imagePullSecrets helps separate image download permissions from other operations in the cluster. This helps secure the environment and minimize the risk of unauthorized access to images.

🔧 Easy Configuration: Allowing users to customize imagePullSecrets from within a project or cluster configuration makes it easier to manage these secrets and provides flexibility.

📈 Scalability: In environments where we use multiple clusters or projects, the ability to configure imagePullSecrets makes it easier to scale and manage access to images across different levels of infrastructure.

This Merge Request improves your design and adapts it to the real needs of your users. This is an important step in ensuring secure and efficient container management. 🎉👏
