This commit updates destroy_vm to remove the redis member from the completed queue only after a destroy has been completed. Without this change a VM that is being destroyed will be logged as discovered when inventory is checked since it has already been removed from the completed queue.
This commit updates destroy_vm to remove references to its mutex tracking object when destroyed. Without this change a VM that is destroyed will leave its mutex tracking object forever causing the pool manager memory footprint to increase.
This commit adds a changelog and contributing guidelines to vmpooler. Without this change vmpooler offers no specific contributing guidelines or changelog.
