util/release: add gerrit stats script
This tool downloads, caches and analyzes commits pushed to gerrit for a specified range of commits. Currently it only works over SSH. Data that is printed about the range of commits: CSV Data about each individual commit: - Commit ID - Commit Date - Author - Commiter - Submitter - Lines added - Lines removed - Title - Reviewers It then prints the analysis it did on the data: - Total Commits - Total lines added - Total lines removed - Total difference - Authors - Number of commits - Total Authors - Authors - Lines added - Authors - Lines removed - Reviewers - Number of patches reviewed - Submitters - Number of patches submitted The script relies on a number of perl modules which must be installed separately.
