run_time_limit config flag appears to be unused

[phiggins]

There is a config flag run_time_limit defined in the attributes file: https://github.com/chef-cookbooks/audit/blob/master/attributes/default.rb#L95

The value is referenced here, and then passed to Reporter::ChefAutomate: https://github.com/chef-cookbooks/audit/blob/master/files/default/handler/audit_report.rb#L261

Reporter::ChefAutomate sets an instance variable with that passed in value, but then never references it: https://github.com/chef-cookbooks/audit/blob/master/libraries/reporters/automate.rb#L27

It appears that should be the final argument passed to strip_profiles_meta, but that is instead hardcoded to 1: https://github.com/chef-cookbooks/audit/blob/master/libraries/reporters/automate.rb#L69
https://github.com/chef-cookbooks/audit/blob/master/libraries/helper.rb#L162
