// Retrieves a list of components that meet the component, version, and platform
// requirements of a deployment. Greengrass core devices call this operation when
// they receive a deployment to identify the components to install. This operation
// identifies components that meet all dependency requirements for a deployment. If
// the requirements conflict, then this operation returns an error and the
// deployment fails. For example, this occurs if component A requires version
// >2.0.0 and component B requires version <2.0.0 of a component dependency. When
// you specify the component candidates to resolve, IoT Greengrass compares each
// component's digest from the core device with the component's digest in the
// Amazon Web Services Cloud. If the digests don't match, then IoT Greengrass
// specifies to use the version from the Amazon Web Services Cloud. To use this
// operation, you must use the data plane API endpoint and authenticate with an IoT
// device certificate. For more information, see IoT Greengrass endpoints and
// quotas (https://docs.aws.amazon.com/general/latest/gr/greengrass.html).
