Added a check project command that checks all flows in a project. Flows can be filtered by prefix or /regular expression/ and flows are now sorted by name. By default all matching flows will be shown with a short histogram of max 5 executions (can be set via -c) and histogram details will be shows for 3 executions (can be set via -d) if the job status is failed. If you're only interested in non-healthy flows you can provide -i (--ignore-healthy).
