Enhancement: Pod additional configuration management supports

[wu8685]

What would you like to be added?

A workload designed to manage additional Pod configurations, such as sidecars, PVC, environment variables, as well as extra labels and annotations. These configurations are independent of the CollaSet control to enable parallel updates.

Why is this needed?

In many scenarios, configurations such as sidecars, associated PVCs, and environment variables are typically handled by separate teams. This approach allows different departments to manage different aspects of Pod configuration independently.
