Duarte Nunes 26c31f6798 Merge "db/hints: Expose current backlog" from Duarte
"
Hints are stored on disk by a hints::manager, ensuring they are
eventually sent. A hints::resource_manager ensures the hints::managers
it tracks don't consume more than their allocated resources by
monitoring disk space and disabling new hints if needed. This series
fixes some bugs related to the backlog calculation, but mainly exposes
the backlog through a hints::manager so upper layers can apply flow
control.
