Valid values for <check> are `test`, `subtest` and `assert`. Valid
<status> keys are defined in the :py:mod:`mozlog.logtypes` module. The
<test> key is the id as logged by `test_start`. Finally the <data>
field is the log data from any `test_end` or `test_status` log messages
that have an unexpected result.
Mozlog's structuredlog has a `known_intermittent` field indicating if a
`test` and `subtest` <status> are expected to arise intermittently.
Known intermittent results are logged as both as `expected` and
`known_intermittent`.
