How can I export historical information about sprints from JIRA Agile? I know that I can export issues from JIRA, and those exported issues have a "Sprint" field with the name of the sprint (or sprints) that it is in. However, I'd like to export information that has a list of all sprints, the issue key for each issue within each sprint, the metadata about the sprint (when it started, when it ended, etc), and all other data related to sprints.
