Arne Welzel 1f5ab4878b logging/ascii: Support leftover log rotation in non-supervisor setups
We have a use case to rotate leftover log files in a non-supervisor
setup. There doesn't seem to be a strict requirement on supervisor
functionality. Allow enabling leftover log rotation through
LogAscii::enable_leftover_log_rotation and redef this for the
logger node in a supervisor setup individually.

##! This is the core Zeek script to support the notion of a cluster logger.
##!
##! The logger is passive (other Zeek instances connect to us), and once
##! connected the logger receives logs from other Zeek instances.
##! This script will be automatically loaded if necessary based on the
##! type of node being started.
##! This is where the cluster logger sets it's specific settings for other
##! frameworks and in the core.
