Lifecycle tests

Lifecycle tests exercise the Pulumi engine and serve as a specification for the behaviours and interactions of the various features that define the lifecycle of a Pulumi program. This includes, but is not limited to:

• The operation(s) being executed (up, preview, etc.) and the options passed to that operation (--target, --target-dependents, etc.).
• The programs being executed -- their resources, invocations, and the various options that might be associated with them (parent, retainOnDelete, etc.).
• The state of the program before and after operations are executed.
