Adding error information to metadata doesn't do much if we write it to disk
first.
Unlike other changes so far on this ticket, this one only modifies
'runQuantum'/connections and leaves 'run' only supporting Exposure as
input.  Fixing that would make everything a lot messier unless we do
a lot of work, like making cell-coadd aperture corrections a true
BoundedField and/or dropping MultipleCellCoadd as a supported
connection type (RFC-1193).
This only touches the connection/runQuantum level; run still only works
on lsst.afw.image.Exposure.
In the long term, it would be better to un-configure those PixelFlags
columns, but that changes the schema and hence isn't viable for
something we want to backport to v30.
