Product Update: Auto archive, order upon PR creation and direct contact

Product Update: Auto archive, order upon PR creation, and direct contact with Axolo's authors are now available in the latest version of Axolo. Configuration words at pull request creation allow users to instruct Axolo not to create Slack channels for specific requests. Auto archival is enabled when a pull request is closed or merged. Direct communication with Axolo's authors can be done through Slack, and updates to the app are required for this feature. Upcoming features include Github Action notifications, merge functionality in Slack channel, notification settings for _axolo, and a weekly leaderboard for teams.
