The tlog-tiles and static-ct-api specs allow partial tiles to be deleted when the corresponding full tile is available. This helps to reduce R2 storage costs, but will incur extra cost for the R2 list and delete operations. - Add a `Cleaner` Durable Object, which iterates over a log and for each full tile available in the public bucket, lists and deletes any corresponding partial tiles. The cleaner tracks subrequests to prevent an alarm from exceeding the 1000 subrequests limit per invocation. - (bonus) Lays the groundwork for implementing a tlog-witness or tlog-mirror as a service that periodically updates based on a target log's latest checkpoint. Other changes: - Update to worker 0.6.1 for R2 `delete_multiple` support and `PartialEq` support for ObjectIds. - Move more Durable Object intialization logic from the MTC and CT applications to the `generic_log_worker` crate to deduplicate code. - Fix tree time metric to seconds.
