Due to Stream 9 storage space and being open for rsync/pull, some of our sponsors reached out to say that we have a limited available bw/data plan per month from now on, so we need to :

• apply a host macro in zabbix to override the default {$ALLOWED_MONTHLY_BW} zabbix macro with specific value
• apply it from ansible inventory settings, so modifying the tool using zabbix api to also support modifying host macros
• eventually take action when we're reaching limit for the month (remove it from dns pool)
