Instrument edit failures

Users on enwiki's VPT are reporting a spike in the frequency of rejected edits
due to loss of session data. It is difficult to corroborate these reports when
we don't have any instrumentation for them in the code, and thus no visibility
into how frequently they are occurring in the wild.
