allow uninstalling AWS objects created by prerequisite playbook
add deprovisioners/uninstallers for objects created via playbooks/aws/openshift-cluster/prerequisites.yml specifically: security groups, vpcs, and any ssh keys introduce openshift_aws_enable_uninstall_shared_objects to protect AWS objects that would be shared in the case of multiple clusters co-existing in one AWS account. right now it protects the ssh keys, but it can/should be used to protect against deleting the shared IAM instance profile as well. default this variable to False to be on the safe side when uninstalling/deprovisioning. add some documentation on using deprovisioning playbooks
