This pull request is an implementation of vector data type similar to one used by Apache Cassandra.
The patch contains:
- implementation of vector_type_impl class
- necessary functionalities similar to other data types
- support for serialization and deserialization of vectors
- support for Lua and JSON format
- valid CQL syntax for `vector<>` type
- `type_parser` support for vectors
- expression adjustments such as:
- add `collection_constructor::style_type::vector`
- rename `collection_constructor::style_type::list` to `collection_constructor::style_type::list_or_vector`
- vector type encoding (for drivers)
- unit tests
- cassandra compatibility tests
- necessary documentation
