This REST endpoint supports partial updates of the checker property set. Only
properties that are set in the [CheckInput](#check-input) entity are updated.
Properties that are not set in the input (or that have `null` as value) are not
touched.

[CheckInput](#check-input) or the value in the request body is omitted.

Reruns a check. As response the [CheckInfo](#check-info) entity is returned that
describes the created check.

Notification options may be specified as [RerunInput](#rerun-input) entity in
the request body.

This REST endpoint supports rerunning a check. It also resets all relevant check
fields such as `message`, `url`, `started` and `finished`.
