    Rework logrotate configuration

    - instead of rotating logs daily and weekly, run the script every 15
      minutes
    - merge weekly and daily configuration files
    - rotate logs basing on two criteria: age (a week; only if file is
      bigger than 10M on master or 5MB on remote nodes) and size (rotate the file
      always if its size exceedes 100M on master or 20M on remote nodes, regardless
      its age)
    - use dateformat to make rotated logs' filenames more readable;
      as logrotate supports only year, month, day and unix epoch, use them
      all
    - fix a lot of lint complaints, including aligments, curly braces and
      proper quoting; give logrotate related files more intuitive names
    - dump.log has been renamed to shotgun.log (LP#1318516)
    - check if there is no logrotate instances running before executing
      cronjob
