Andrew Kryczka	e18a4df62a	workaround race conditions during `PeriodicWorkScheduler` registration (#7888) ... Summary: This provides a workaround for two race conditions that will be fixed in a more sophisticated way later. This PR: (1) Makes the client serialize calls to `Timer::Start()` and `Timer::Shutdown()` (see https://github.com/facebook/rocksdb/issues/7711). The long-term fix will be to make those functions thread-safe. (2) Makes `PeriodicWorkScheduler` atomically add/cancel work together with starting/shutting down its `Timer`. The long-term fix will be for `Timer` API to offer more specialized APIs so the client will not need to synchronize.

Andrew Kryczka	1e00909730	Periodically flush info log out of application buffer (#7488) ... Summary: This PR schedules a background thread (shared across all DB instances) to flush info log every ten seconds. This improves debuggability in case of RocksDB hanging since it ensures the log messages leading up to the hang will eventually become visible in the log. The bulk of this PR is moving monitoring/stats_dump_scheduler* to db/periodic_work_scheduler* and making the corresponding name changes since now the scheduler handles info log flushing, not just stats dumping.
