Trending: Prepare static content for the new UTI
- Chapter "jenkins jobs": deleted, the neccesary information is in
"Performance Tests".
- Chapter "perpatch_performance_tests": deleted, should be somewhere
else.
- Chapter "testbed_hw_configuration": no information was there for years.
- Chapter "performance_tests": deleted.
- Other chapters: Edited, updated, simplyfied.
