HOTFIX : Bypass permission for training accuracy graph download

[kshitijrajsharma]

What does this PR do ?

• Implements bypass logic to allow user downloading the accuracy graph without an authentication
• Removes the pagination on banner endpoint
• Implements caching on training-workspace view

Consideration :

I have bypassed the logic for accuracy graphs , this should allow user without an authentication to access the single file , however for other files it requires login still !
I am not fully confident on cache , server cache is not a best way to cache the training workspace view , I recommend cache on the frontend page itself ! However in-order to make user experience smooth and reduce frontend development load I have implemented the cache in server to the workspace view for now !

Later on , streaming EFS to endpoint will be more efficient than manually going through the folders from python , This can be added as enhancement for this endpoint , I am aware that this endpoint will not be efficient when training files keep growing on the server !

How to test ?

Try fetching the accuracy graph without an authentication it should work !

Great for ramp,
We might need to visit this again when we implement Yolo, depends on what graph we will have in Yolo
