apply logrotate to log folders

[ofrei]

123andy has nice logic for handling logs - they are collected in a single folder
https://github.com/123andy/redcap-docker-compose/blob/master/rdc/docker-compose.yml
and cleaned using logrotate ( https://linux.die.net/man/8/logrotate )
https://github.com/123andy/redcap-docker-compose/tree/master/rdc/docker-cron

Same as #16 this isn't something to implement right now - we can do it much later if logs ever become a problem
