Add a KeyValueStoreInterface::has() method [#2216459]

Objective

#2190723: Add a KeyValueStore\FileStorage to replace e.g. ConfigStorage discovered the need for being able to check whether a key/value store has a key (without retrieving the value).
Such a method can be easily supported by any key/value store — worst case implementation is to actually get the key and check whether it has a value.

Proposed solution

Add a new has() method to KeyValueStoreInterface.

I just wtf'd really hard when I went to use this and it didn't work.

I even went ahead and wrote a draft change notice, just in case anyone was using this and wondering about the absence of has():
