Zane Bitter b0d7ffadc3 Pre-empt in-progress nested stack updates on new update
If the parent resource of a nested stack is locked due to an IN_PROGRESS
update, cancel the nested stack update (which will result in the parent
resource being marked FAILED and releasing the lock so that the new
traversal can begin acting on it).

This effectively results in the model for simultaneous updates in a
single stack (that we wait for in-progress work when it would conflict,
but otherwise don't delay starting a new update) being extended
recursivey down through nested stacks.
