Store machine description info in cache and json reports.

This CL updates the cache mechanism to store the machine spec
info (the checksum string) in the cache, as well as storing the
machine information in the json reports (to go into the dashboard
archive).  It also updates the json reports to always include the
full set of result fields for a test, and it verifies that the
old cache directory exists before trying to remove it.

BUG=None
TEST=Tested in my directory, with --cache_only=True, --rerun=True and
--json_report=True
