/**
* Fetch a list of containers for this user.
*
* By default, this fetches the entire list of containers for the
* given user. If you have more than 10,000 containers (who
* wouldn't?), you will need to use $marker for paging.
*
* If you want more controlled paging, you can use $limit to indicate
* the number of containers returned per page, and $marker to indicate
* the last container retrieved.
*
* Containers are ordered. That is, they will always come back in the
* same order. For that reason, the pager takes $marker (the name of
* the last container) as a paging parameter, rather than an offset
* number.
*
* @todo For some reason, ACL information does not seem to be returned
* in the JSON data. Need to determine how to get that. As a
* stop-gap, when a container object returned from here has its ACL
* requested, it makes an additional round-trip to the server to
* fetch that data.
*
* @param int $limit The maximum number to return at a time. The default is
* -- brace yourself -- 10,000 (as determined by OpenStack. Implementations
* may vary).
* @param string $marker The name of the last object seen. Used when paging.
*
* @return array An associative array of containers, where the key is the
* container's name and the value is an \OpenStack\ObjectStore\v1\ObjectStorage\Container
* object. Results are ordered in server order (the order that the remote
* host puts them in).
