feat: Implemented option to auto refresh the UI after any backup

- Added an env var: AUTO_REFRESH to .env.sample (defaults to false)
- Added helper script helpers/shells/cronjob.sh to call the
  borgwarehouse api for refreshing the repo status and used storage
- Added function to add this feature when creating new repositories (if
  enabled) in helpers/shells/createRepo.sh
- Added function to enable/disable this option during startup (depends
  on the configured bool for AUTO_REFRESH) in docker/docker-bw-init.sh.
	- This basically inserts or removes an additional command per
	  forced-ssh-command that calls the previous created
	  "cronjob.sh" helper script.
