Clean up weird test code

While fixing something else, the strange code in the test suite
presented itself. Looks like a massive copy-paste error and a couple
of random oddities.

!! Changed db_preallocation to False

Long explanation, but hopefully answers any questions.

We don't like changing the default behavior of Swift unless there's a
really good reason and, up until now, I've tried doing this with this
new db_preallocation setting.

For clusters with dedicated account/container servers that usually
have fewer disks overall but SSD for speed, having db_preallocation
on will gobble up disk space quite quickly and the fragmentation it's
designed to fight isn't that big a speed impact to SSDs anyway.

For clusters with account/container servers spread across all servers
along with object servers usually having standard disks for cost,
having db_preallocation off will cause very fragmented database files
impacting speed, sometimes dramatically.

Weighing these two negatives, it seems the second is the lesser evil.
The first can cause disks to fill up and disable the cluster. The
second will cause performance degradation, but the cluster will still
function.

Furthermore, if just one piece of code that touches all databases
runs with db_preallocation on, it's effectively on for the whole
cluster. We discovered this most recently when we finally configured
everything within the Swift codebase to have db_preallocation off,
only to find out Slogging didn't know about the new setting and so
ran with it on and starting filling up SSDs.

So that's why I'm proposing this change to the default behavior.

We will definitely need to post a prominent notice of this change
with the next release.

Expand recon middleware support

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.
