Delete all job results, model snapshots and forecast data that have exceeded
their retention days period. Machine learning state documents that are not
associated with any job are also deleted.
You can limit the request to a single or set of anomaly detection jobs by
using a job identifier, a group name, a comma-separated list of jobs, or a
wildcard expression. You can delete expired data for all anomaly detection
jobs by using `_all`, by specifying `*` as the `<job_id>`, or by omitting the
`<job_id>`.
