intial version to support walk milestone and beta version

[jeremiaswerner]

remove experimental (crawl) items

• remove all crawl+ configmap and secret
• remote ssh key
• remote jumpbox

add beta (walk) items:

• separate taskstore, input and output bucket and PDS
• change tutorials to use beta command group
• change tutorials to use input and output buckets and volume mounts
• create codeengine-fleet-defaults secret
• update all hello world examples including wordcount
• update docling tutorial
• updated diagrams to match usage of Persistent Data Stores

What's missing is the inferencing and simulation tutorial... I've removed them for now and we can add them back step by step.

Really cool!

Only found some minor discrepancies between echo output and actual applied values.

Once this is in for a few days, we should consider to put a info text on top of the experimental readme stating that there is a beta version available. Alternatively, we could apply a symlink pointing the user to the beta readme right-away.

@reggeenr @stevenwhitehead thank you for the review. I incorporated the feedback.

I also changed the rclone environment to be more dynamic. It now generates a rclone config per resource group. The upload and download script lookup the targeted resource group, the buckets and use the corresponding rclone environment.

This allows to setup and switch between multiple resource groups.

Pls have a final look and feel free to merge...
