Zabbix DirSize folder size monitoring

LEGACY CONTENT! See actual Ansible repository!

Discovery rule reads the list of configured folders on the client (/etc/zabbix/dirsize-list).
Data item (get) triggers the calculation and value sending to the trapper.

Template: [template_linux_dirsize] FIXFILE template_linux_dirsize.zip Folder list discovery period: 1 hour.
Value polling period: 20 minutes.
