fix: Keep Docker Sidecar Alive for Data Retrieval

[ishaansehgal99]

Reason for Change:

• Keep the docker sidecar container alive so incase ACR push fails we can still exec into the container to retrieve completed tuning job files in the /mnt/results folder.

• Perform validation check for output images that are uppercase

• Use projected volume for mounting docker config secrets - mount at directory location /root/.docker/config

• Add secret for E2E Temp ACR
