IGlobalCacheTryReplace Method

Attempt to replace the value for a given key. This method is thread-safe. Note that there is no guarantee that any call to TryReplace method will succeed; it will fail (return false) if another thread changed the underlying value (oldValue). To guarantee a successful replacement, TryGet and TryReplace methods need to be called in a loop until TryReplace returns true. Alternatively, ReplaceValue method may be called, which executes such loop internally.
