Tucson pod OLT out of disk space

The OLT on the Tucson pod ran out of disk space over the holidays. The issue seems to be that the BAL logs are going to syslog rather than a separate logfile, and that syslog is not being rotated.

The reason for BAL logging to syslog seems to be that /etc/init.d/dev_mgmt_daemon specifies argument "-syslog" by default.

I think the solution is to redirect the logging to /var/log/bal_core_dist.log. There is already a logrotate configuration for this file (/etc/logrotate.d/openolt), so that should conserve disk space.
