variable name collision for setting logs

[tugytur]

Proposed changes

• Change public cert permission
• Fix variable name collision

Change the permission for the uploaded public certificate to 0644 because certain applications try to read the whole /etc/ssl/certs directory and throw warnings if some certs can't be read.

Resolve template error where loop variables log were shadowing the parent log dictionary, causing "object of type 'str' has no attribute 'error'" failures. Changed loop variable names to access_item and error_item to avoid naming conflicts. Don't enforce gzip variable to be a string.
