Reduce noise in nightly log file

[danistrebel]

The log file is quite long at the moment making it hard to find the reason for failing nightlies

$ LOG_LINES=$(cat $LOG_FILE | wc -l)                                                                                                                                                                                                      
$ echo $LOG_LINES

Upon visual inspection there are a still a lot of MVN transfer process logs (can be disabled in mvn > 3.6.1)

$ MVNTP_LINES=$(cat $LOG_FILE | grep "Progress (" | wc -l)
$ echo "$MVNTP_LINES ($(($MVNTP_LINES*100 / $LOG_LINES))%)"

Even though the TP logs are disabled in Sackmesser the following projects still emit verbose TP logs:

• cicd-pipeline
• cicd-sharedflow-pipeline
• product-recommendations

Looks like it worked. Checking tonight's nightly log

$ cat $LOG_FILE_AFTER_PR | wc -l
