`filter` can be used to specify a subset of queues. Any
[Queue][google.cloud.tasks.v2.Queue] field can be used as a filter and
several operators as supported. For example: `&lt;=, &lt;, &gt;=, &gt;, !=, =, :`. The
filter syntax is the same as described in [Stackdriver's Advanced Logs
Filters](https://cloud.google.com/logging/docs/view/advanced_filters).

Sample filter "state: PAUSED".

Note that using filters might cause fewer queues than the
requested page_size to be returned.
