Remove old redundant deployment file.

[Tatsinnit]

This PR removes a very old deployment yaml file for periscope.

WE kept it as a grace period for its retirement but now the underlying image is also not reachable and the repo uses the kustomize way to build the deployment file as consumption.

Thank you

@peterbom if you can please review ❤️🙏☕️ this will also avoid confusion like happened here: #160
