Request Adding Log Rotation to Thredds container of Ansible Installation

[jasoncunning]

The thredds container of the ESGF data node emits enough logging to STDOUT that it has filled the /var partition (40G) of the host on which we've installed it twice since August. This obviously causes a failure of the service--we have to manually reset the log file to zero bytes and restart the container. Request that the thredds container be configured in the Ansible installation to run with the log rotation feature of the default log driver "json-file" enabled, say keeping a maximum of 10 log files of 10m size or something appropriate or even implementing variables for these values so we can set them to our liking.
