odsComponentStageBuildOpenShiftImage: jenkins build log cropped

[tbugfinder]

Describe the bug
We've been building an OSS project which spits out loads of console output during build.
After the build jenkins log does not include all of the output of the build pod terminal output itself. It seems that there's a limit.

To Reproduce
Steps to reproduce the behavior:

1. Build odsComponentStageBuildOpenShiftImage
2. Output 20mb to 50mb to console
3. Compare build pod output with jenkins log output

Expected behavior
Jenkins log should include all of the build log.
