Gian Merlino 3aa7017975 Remove some unnecessary task storage internal APIs. (#6058) 
* Remove some unnecessary task storage internal APIs.

- Remove MetadataStorageActionHandler's getInactiveStatusesSince and getActiveEntriesWithStatus.
- Remove TaskStorage's getCreatedDateTimeAndDataSource.
- Remove TaskStorageQueryAdapter's getCreatedTime, and getCreatedDateAndDataSource.
- Migrated all callers to getActiveTaskInfo and getCompletedTaskInfo.

This has one side effect: since getActiveTaskInfo (new) warns and continues when it
sees unreadable tasks, but getActiveEntriesWithStatus threw an exception when it
encountered those, it means that after this patch bad tasks will be ignored when
syncing from metadata storage rather than causing an exception to be thrown.

IMO, this is an improvement, since the most likely reason for bad tasks is either:

- A new version introduced an additional validation, and a pre-existing task doesn't
  pass it.
- You are rolling back from a newer version to an older version.

In both cases, I believe you would want to skip tasks that can't be deserialized,
rather than blocking overlord startup.

* Remove unused import.

* Fix formatting.

* Fix formatting.
