This combines a general refactor of our workload status checks, more
robust checking of related resource statuses (in order to fail fast on
common errors like ImagePullBackOff and CrashLoopBackOff), as well as an
improvement on the level of information given when errors do come up.
This should aid considerably in debugging deployment issues.
Closes #863
To test, I recommend breaking modules in any way you can think of, For example, make the command/args invalid such that the container doesn't start, have the container crash right after start, specify an invalid image (to trigger ImagePullBackOff) etc.
