Description

It looks like the the thread dump /executors/threadDump/?executorId=[id] is only available in the UI, not in the rest api at all. This is especially a pain because that page in the UI has extra formatting which makes it a pain to send the output to somebody else (most likely you click "expand all" and then copy paste that, which is OK, but is formatted weirdly). We might also just want a "format=raw" option even on the UI.
