v0.5.0

• Instance refresh: don't set a default minimum healthy percentage of 100% anymore. The minimum healthy percentage is now determined from the instance maintenance policy of the ASG. If no instance maintenance policy, the value defaults to 90%.
• Introduce the properties min_healthy_percentage and max_healthy_percentage on the autoscale definitions for tuning these settings. The property healthy_percentage is now deprecated and should be changed to min_healthy_percentage.
• Fail deployment if instance refresh fails by @lloydwatkin in #8.
• Add tags to the AMI with information about the current application, stage & deployment:
  • capistrano-asg-rolling:application
  • capistrano-asg-rolling:stage
  • capistrano-asg-rolling:deployment-branch
  • capistrano-asg-rolling:deployment-release
  • capistrano-asg-rolling:deployment-revision
  • capistrano-asg-rolling:deployment-user
• The tag capistrano-asg-rolling:version has been renamed to capistrano-asg-rolling:gem-version.
• Updates to the documentation.
