AWS S3 bucket by HTTP template was initially developed to work in bundle with 'parent' one AWS by HTTP .
It has LLD rule that automatically creates hosts for discovered buckets and links AWS S3 bucket by HTTP with corresponding macro value
But we have no clear explanation if AWS S3 bucket by HTTP can be used separately and we have no default value for {$AWS.S3.FILTER.ID} to make the template working
Also please add {$AWS.S3.FILTER.ID} macro explanation to 'git' documentation

Also it will be very helpful to add 'real life' example of AWS monitoring configuration to Zabbix documentation
