Joe e12da7c9a3 NIFI-985: Custom log prefix for LogAttribute processor
The LogAttribute processor evaluates the log prefix EL using the current flow file.

Log prefix helps to distinguish the log output of multiple LogAttribute processors and identify the right processor. Log prefix appears in the first and the last log line, followed by the original 50 dashes. If you configure log prefix 'STEP 1: ' the log output looks like this:

STEP 1 :  --------------------------------------------------

        Value: '9'
