If the `node['nginx']['disable_access_log']` attribute is set to `false` the Nginx `access_log` directive is removed from the configuration file. However, this does not disable the access logs. Nginx enables access logs by default if the directive is not present as evident in their [docs](http://nginx.org/en/docs/http/ngx_http_log_module.html#access_log).

This pull requests fixes this issue and gives users the ability to add logging options to both the `error_log` and `access_log` directives.
