This command works exactly like {@link #sunion(const(ubyte)[]...) SUNION} but instead of being returned
the resulting set is stored as dstkey. Any existing value in dstkey will be over-written.

Time complexity O(N) where N is the total number of elements in all the provided sets
@param dstkey
@param keys
@return Status code reply
