KUDU-2297 (part 3): refactor process-wide stack collection out of /stacks

Previously a bunch of logic to collect all the stacks from the process
was in the /stacks path handler. This logic is relatively generic and
shouldn't be intermingled with the formatting code. In particular I'd
like to use it in the diagnostics log, where a different output format
is desirable.

this assertion failed for me under load, it appears that somehow we are 
sometimes racing against the other thread collecting stacks here
