Add http API for checking if a key exists #304

Currently I have to use GET <api URL>/node/<UUID>/<data name>/key/<key> to check if a key exists, which is time consuming for a key mapped to a heavy value. Supporting HEAD method or something like GET <api URL>/node/<UUID>/<data name>/haskey/<key> can solve the problem.

The github formatting ate your markdown. Could you try again?
