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

That parameter tells the log library to call a 'hook' function (if true).
Default is true, and I've changed it to false to avoid calling the hook function.
I believe this was a bug in the library.
However, our broker doesn't use lm hook functions, so to the broker this change is NULL.
