-- Returns a list of Jobs. Use the JobsID and fromDate and toDate filters
-- to limit which jobs are returned. The response is sorted by
-- creationDataTime - latest date first. Jobs are created by the
-- StartRecovery, TerminateRecoveryInstances and StartFailbackLaunch 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.
