Paul Hinze	97acccd3ed	core: targeted operations ... Add `-target=resource` flag to core operations, allowing users to target specific resources in their infrastructure. When `-target` is used, the operation will only apply to that resource and its dependencies. The calculated dependencies are different depending on whether we're running a normal operation or a `terraform destroy`. Generally, "dependencies" refers to ancestors: resources falling _before_ the target in the graph, because their changes are required to accurately act on the target. For destroys, "dependencies" are descendents: those resources which fall _after_ the target. These resources depend on our target, which is going to be destroyed, so they should also be destroyed.	2015-03-31 14:49:38 -05:00
