Output only. The host that the task is sent to.

The host is constructed from the domain name of the app associated with
the queue's project ID (for example &lt;app-id&gt;.appspot.com), and the
[service][google.cloud.tasks.v2beta3.AppEngineRouting.service],
[version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and
[instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. Tasks
which were created using the App Engine SDK might have a custom domain
name.
