Allow different default null tokens to be configured for each field type

Description

The configuration property Environment.DEFAULT_NUMERIC_NULL_TOKEN was designed to configure a default for text-based keywords, but is now being applied to numeric tokens which happen to encode null values as well.
We should consider having independent defaults and global options to specify the defaults for each field type.
