boost::any for cassandra and more:

- replaced void* with boost::any for type safety (might be just a bit less efficient)
- replaced a multi-index-container used for statement parameters ( with position index and name index ) and a vector of the same parameters with a compile-time type-based map
- refactored lease manager to use exchanges
- exchanges now support UDTs (user defined types) and collections to be used in Cassandra statements
- replaced size-ambiguous types (e.g. int) with size-explicit types (e.g. int32_t) in Cassandra-related code
- made exception messages and log messages more detailed and consistent in format
