-- Displays detailed information about a specified job template. 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.
