Remove old headless log infrastructure

[csweichel]

This PR removes the last leftovers of the old headless log infrastructure.

fixes #4911

Noteworthy:

• there's a protocol change on ws-manager's SubscriptionResponse which removes the oneof. To my understanding that doesn't affect what's on the wire, i.e. the protocol should remain backwards compatible. That's because neither numbers nor types of the fields change.

Maybe unrelated, but I'm not able to start a prebuild workspace on https://csweichel-remove-old-headless-log-4911.staging.gitpod-dev.com/#prebuild/https://github.com/gitpod-io/gitpod/tree/gpl/test-prebuild

The image build pod does not terminate. Logs read:

Ok, now it started. 🤷 The image build hang for 14-20 mins, but somehow finished, and the prebuild ran flawlessly afterwards.

The second run worked flawlessly.

[geropl]

Tested, works. The hickups are related to image-builder mk3, not this PR.
