Make sure that empty but still valid results (like no unmounted drives)
aren't treated as 500 errors.

Expand recon middleware to include support for account and container
servers in addition to the existing object servers. Also add support
for retrieving recent information from auditors, replicators, and
updaters. In the case of certain checks (such as container auditors)
the stats returned are only for the most recent path processed.
The middleware has also been refactored and should now also handle
errors better in cases where stats are unavailable.
While new check's have been added the output from pre-existing
check's has not changed. This should allow existing 3rd party
utilities such as the Swift ZenPack to continue to function.

My first stab at unittests for the recon middleware.
Also, made some minor changes to the middleware to make testing
easier now and down the road.
