Async equivalent of TwoLevelCache for use with coroutine populate functions: same soft/hard TTL semantics, but coordinated with asyncio primitives instead of a ThreadPoolExecutor. Co-authored-by: Loxeris <30194187+Loxeris@users.noreply.github.com>
Adds a generic diracx.core.sources module with AsyncCacheableSource and Snapshot, a diracx.cacheable_sources entry-point group, and application factory support: each source is instantiated once per app (so its caches persist across requests) with the database instance matching its db_class, and its read method overrides the create dependency for every implementation class so extensions can substitute their own sources. Routers depending on a source whose database is not available fail at startup, consistent with the handling of missing databases. Co-authored-by: Loxeris <30194187+Loxeris@users.noreply.github.com>
