Description

Typical map implementations return the value that was removed when performing a remove. Because you couldn't update the existing remove methods without it being a breaking change I suggest adding new versions of the remove and removeByPattern methods that return the removed value(s).

These changes should also be applied up the chain to any class that makes use of these classes such as the MapCacheServer and AtomicDistributedMapCacheClient.
