> Currently the {{BlockCollection}} interface returns {{BlockInfoContiguous}} objects in
multiple calls.
> In order to decouple block manager and the namespace, the interface should return the
{{Block}} instead of {{BlockInfoContiguous}} objects, where the latter contain information
like the locations of DN.
> This jira proposes to clean up the interface and to return the {{Block}} objects directly.
