(MODULES-9104) Add file_mode to config files. (puppetlabs#1922)

- ::apache::file_mode attribute is missing from several config files, including the main config file in ::apache, any custom config files managed by apache::custom_config, and reqtimeout.conf managed by apache::mod::reqtimeout
- Add "mode => $::apache::file_mode" to ::apache, apache::custom_config, and apache::mod::reqtimeout to correct the inability to manage the mode of these config files.
