-- Lists job templates based on a set of parameters. Job template stores
-- values of StartJobRun API request in a template and can be used to start
-- a job run. Job template allows two use cases: avoid repeating recurring
-- StartJobRun API request values, enforcing certain values in StartJobRun
-- API request.
--
-- This operation returns paginated results.
