DEV: Prevent defer stats exception when thread aborted ( #19863 )
...
When the thread is aborted, an exception is raised before the `start` of a job is set, and therefore raises an exception in the `ensure` block. This commit checks that `start` exists, and also adds `abort_on_exception=true` so that this issue would have caused test failures.

FEATURE: add basic instrumentation to defer queue ( #19824 )
...
This will give us some aggregate stats on the defer queue performance.
It is limited to 100 entries (for safety) which is stored in an LRU cache.
Scheduler::Defer.stats can then be used to get an array that denotes:
- number of runs and completions (queued, finished)
- error count (errors)
- total duration (duration)
We can look later at exposing these metrics to gain visibility on the reason
the defer queue is clogged.

Use a dedicated thread to run Scheduler::Defer
This avoids blocking of a worker during operations that require waiting.
In particular uploads risked blocking a unicorn.
This also add a queue "length" that discourse prometheus consumes.
