Hi, @ajkh88 and @charlesconnell, could you help take a look when free, thanks!

Pull request overview

Updates region-reopen call sites to consistently use the throttled reopening implementation (HBASE-29809), so region reopening honors configured throttling.

Changes:

• Switch RegionsRecoveryChore to call HMaster.reopenRegionsThrottled instead of the unthrottled reopen method.
• Update TestRegionsRecoveryChore expectations to verify throttled reopen calls.
• Deprecate HMaster.reopenRegions(...) in favor of reopenRegionsThrottled(...) and fix minor logging constant/message typos in the chore.

Oh, I see, there is a java doc warning, let me remove this time.
