[CURATOR-598] InterProcessSemaphoreV2::getData to check against data changes on the semaphore

[jira-importer]

InterProcessSemaphoreV2 allows holders to set data on the acquired lease: exposing an Optional getData would allow an observer to check against mutex state change despite not being the lock owner (assuming owner has used setData prior a mutex acquisition).
This can be used to weakly enforce order of mutex acquisition or just check owner's identity and/or presence (assuming owner setData prior a mutex acquisition).
