feat(backend): Introduce http client refresh on repeated error (#10481)

HTTP requests can fail when the DNS is messed up. Sometimes this kind of
issue requires a client reset.

+This module tests the thread-local caching functionality including:
+- Basic caching for sync and async functions
+- Thread isolation (each thread has its own cache)
+- Cache clearing functionality
+- Exception handling (exceptions are not cached)
+- Argument handling (positional vs keyword arguments)
