If is_nullable and collation options are not set, then they are
inherited from the space format, if applicable for that field type.

Information about index field types is scattered in two places:

• https://www.tarantool.io/en/doc/latest/reference/reference_lua/box_space/create_index/#box-space-index-field-types
• https://www.tarantool.io/en/doc/latest/concepts/data_model/indexes/#indexed-field-types

It's better to have this info in one place. See also: https://www.tarantool.io/en/doc/latest/concepts/data_model/value_store/#field-type-details
