taskList
.
This initiates a long poll, where the service holds the HTTP connection open and responds
as soon as a task becomes available. The maximum time the service holds on to the
request before responding is 60 seconds. If no task is available within 60 seconds,
the poll will return an empty result. An empty result, in this context, means that
an ActivityTask is returned, but that the value of taskToken is an empty string. If
a task is returned, the worker should use its type to identify and process it correctly.
