Chore

[kravets-levko]

Each commit is a separate change:

• Get rid of redundant lib/hive/Types - some types there were just re-exports, some were used in the only place, some were unused at all. The only type that was used more than once was replaced by a function
• Allow any number type (number, bigint, Int64) for maxRows and queryTimeout (related to Documentation on timeout options needs clarification #167)
• Move some global constants to client config
• Add a note about queryTimeout option (also related to Documentation on timeout options needs clarification #167)
• Use a dedicated AuthenticationError class instead of a generic Error for errors in auth-related code
