nginx configuration dependencies unresolvable with alphabetically sorted processing of pillars

[johnkeates]

If you want to set some sort of an option in nginx that depends on another option being set before, it breaks if the options don't follow each other alphabetically.

For example, access_log has an option to define a custom format. But the custom log format gets ordered below the access_log entry due to sorting happening in either the map.jinja or in the sls_block/nginx macro. This way, access_log can never find it's custom settings because it's always defined below it (since access_log starts with an A).

This is the same as issue #40
