Stream imagebuild logs directly from pods

[geropl]

Description

Streams log URLs from the imagebuild workspace directly instead via image-builder-mk3, which made it cluster dependent.

Basically

• old: server -> (cluster-local) image-builder-mk3 -> imgbuild workspace
• new: server -> imgbuild workspace

Related Issue(s)

Fixes #7874

How to test

• start an image build: https://gpl-7874-imagebuild-logs.staging.gitpod-dev.com/#https://github.com/geropl/roborally
• notice how the image build starts and logs are streamed shortly after. Once the build finished (failed), the state is reflected accordingly
• note: connecting to an already running image build does not seem to work atm because the build(...) call never returns from imagebuilder. I tried to find the root cause, but ultimately it's out-of-scope here.

did not actually try this, but image-builder and API changes look good.
