[preview-install] Add user-friendly output
Part of #9075 This PR adds user friendly output to the preview install docker container by adding a new program prettylog that looks at the output of the entry-point.sh and just adds status updates and spinners. This feels easier instead of adding the same status updates in bash. The status updates are also kept as simple as possible and any additional instructions (URL, and certs) will be added to the documentation instead of here. Feel free to post here if you think it would be better to have them here in the script. Signed-off-by: Tarun Pothulapati <[email protected]>
