Instead of having `exists` as datatype, we can have a flag that indicates
checking only availability. It can be optimized for STRING and HASH type with
exists and hexists, and also available anyway for other types (lookup and
simply check that whether it's not null or null).
Or we even have new filter Bolt that filters tuples by availability. Might
be more clearer.
@darionyaphet @abhishekagarwal87 What do you think?
