Enhance Dataloader Configuration

[surajpaib]

🚀 Feature Request

A lot of dataloader arguments are mentioned in system parameters. For example, batch_size, drop_last_batch.

Would be good to have a way to set other parameters of the dataloader such as prefetch_factor, persist_workers and potentially other future additions to this.

🛰 Alternatives

Maybe we can add a partial dataloader to the system config? and give it dataset and sampler later?
