first step towards new log with transaction id in logfile

### Description
First step towards new log file format
  - removed verbose (rest requests still to be removed)
  - new layout of the lines in the log file
  - transactionId stored and made part of the log file

startTime is the variable for uptime.
startTime doesn't contain milliseconds, so it was no good for the "log start time".
What I could do is to remove startTime and use 'logStartTime.tv_secs' instead.
