Bump oban from 2.15.2 to 2.15.3

[dependabot]

Bumps oban from 2.15.2 to 2.15.3.

Release notes

Sourced from oban's releases.

v2.15.3

Enhancements

• [Pruner] Prune jobs using the scheduled_at timestamp regardless of state.

  The previous pruning query checked a different timestamp field for each prunable state, e.g. cancelled used cancelled_at. There aren't any indexes for those timestamps, let alone the combination of each state and timestamp, which led to slow pruning queries in larger databases.

  In a database with a mixture of ~1.2m prunable jobs the updated query is 130x faster, reducing the query time from 177ms down to 1.3ms.

• [Lite] Avoid unnecessary transactions during staging and pruning operations

  Contention between SQLite3 transactions causes deadlocks that lead to period errors. Avoiding transactions when there isn't anything to write minimizes contention.

Bug Fixes

• [Foreman] Explicitly pause queues when shutdown begins.

  A call to Producer.shutdown/1 was erroneously removed during the DynamicSupervisor queue refactor.

• [Job] Preserve explicit state set along with scheduled_in time.

  The presence of a scheduled_in timestamp would always set the state to scheduled, even when an explicit state was passed.
