-- Returns a list of Jobs. Use the JobsID and fromDate and toData filters
-- to limit which jobs are returned. The response is sorted by
-- creationDataTime - latest date first. Jobs are normally created by the
-- StartTest, StartCutover, and TerminateTargetInstances APIs. Jobs are
-- also created by DiagnosticLaunch and TerminateDiagnosticInstances, which
-- are APIs available only to *Support* and only used in response to
-- relevant support tickets.
--
-- This operation returns paginated results.
