The deployment guide docs now only said that we need the IDF and PDF to do the installation, But it's very difficult for users to prepare these 2 files especially newcomer.

It's very important to guide users what the IDF and PDF should be and how to prepare them by explaining each section.

The guide should split into 2 parts, one is for k8s installation only and one is for full installation (including infrastructure provisioning and k8s provisioning).

The guide of the k8s installation only will simplify the configuration and preparation.
