Ansible does not support 'when' at the play level — moved
teardown_after_scan condition onto each individual teardown task.
Teardown Linode task now reads token from LINODE_TOKEN env var via
lookup('env') instead of the linode_token extra-var (which is now
filtered out of extra-vars by _SECRET_KEYS). AWS teardown removes
hardcoded aws_access_key/secret_key params — those are already set
as environment vars by set_provider_environment().
