The updated docs should cover several things (verify when we actually get to this):

1. Remove guides for using fluffy. If not remove - put them somewhere else, mark them as being deprecated and remove T time later.
2. Replace enterprise related setups / diagrams that mention fluffy with the new setup for lakeFS-Enterprise.
3. Create a dedicated migration section for moving from fluffy to no-fluffy. It must contain the following sections:

• Configuration mapping: from fluffy.yaml into new lakefs.yaml and any new config that should be set.
• Helm OSS: old values -> new values, step by step to upgrade

4. Document configuration of new fields introduced in here

User stories for the docs

1. As a new lakeFS-Enterprise user (regardless if moving from OSS or starting fresh from lakeFS-Enterprise) I want to setup lakeFS-Enterprise with all the features I need (SSO, IAM Auth, MSB, etc)
2. As an existing fluffy user I want to to migrate to no-fluffy, I am using: [the OSS Helm chart | My own Helm Chart | Serverless Env (AWS ECR) | Non K8S (managing lakefs.yaml and fluffy.yaml) ]
