fix(upgrades): callback is not triggering correctly
remove callback
Fix request.lua to handle trying to open a stupid file
prefix syms with name symbol-
drop timeoutCallback
Add crash version to dump.

Dumps should have a version.  The agent that reports the dump is not necessarily the version that died.  I tried to use dependent settings in gyp to avoid duplication, but couldn't get it to work :-/
Every metric except 'files' is in KB.
move self.timeout to local instance variable
