* Add a list of in-flight operations to the deployment This commit augments 'DeploymentV2' with a list of operations that are currently in flight. This information is used by the engine to keep track of whether or not a particular deployment is in a valid state. The SnapshotManager is responsible for inserting and removing operations from the in-flight operation list. When the engine registers an intent to perform an operation, SnapshotManager inserts an Operation into this list and saves it to the snapshot. When an operation completes, the SnapshotManager removes it from the snapshot. From this, the engine can infer that if it ever sees a deployment with pending operations, the Pulumi CLI must have crashed or otherwise abnormally terminated before seeing whether or not an operation completed successfully. To remedy this state, this commit also adds code to 'pulumi stack import' that clears all pending operations from a deployment, as well as code to plan generation that will reject any deployments that have pending operations present. At the CLI level, if we see that we are in a state where pending operations were in-flight when the engine died, we'll issue a human-friendly error message that indicates which resources are in a bad state and how to recover their stack. * CR: Multi-line string literals, renaming in-flight -> pending * CR: Add enum to apitype for operation type, also name status -> type for clarity * Fix the yaml type * Fix missed renames * Add implementation for lifecycle_test.go * Rebase against master
