worker: POST to create image times out and blocks worker for build timeout interval

[tmapes]

Description

Build was started by git webhook.
Init step printed out info as expected, but the UI only ever showed the Init step as running.
All other steps were left gray  and had no logs.

After 30 mins (repo timeout) the build was terminated with the following error:
error:Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.40/images/create?fromImage=docker.io%2Fdocker-android&tag=jdk17": context deadline exceeded

Value

Build was not terminated for a full timeout interval.
Worker was unable to complete more work until this build was terminated.
