Major Bug Fixes

• Fixes chaoslib task files to successfully cleanup chaos resources (daemonsets) in case of infra chaos experiments
• Fixes chaoslib task files to end plays/experiment upon not meeting expected conditions/results rather than notify & proceed with play.
• Move to apps/v1 for deployment/daemonset resources to support recent Kubernetes versions (1.16+)
• Fixes inability to cleanup experiment job when .spec.jobCleanupPolicy is set to delete with Go chaos runner
• Fixes reuse of facts/ playbook, included & registered variables by setting up a new naming convention to pass details from experiment logic playbooks to task files
• Update the docs with correct values for Mandatory/Optional nature of experiment environmental variables
• Fix broken/dead links on the charthub and docs

Community

• Monthly community sync-up (every 3rd Wednesday) to go over the concluded release, roadmap discussion, contributor shoutout, presentations/demos
