Conditional Restrictions - Add conditional restriction logic to field meta schemas and implement validation logic

[joneubank]

Objective

Introduces Conditional Restrictions to the Lectern meta schema. All field types can now optionally contain conditions for applying restrictions based on the value of other fields in the same record.

The validation library has been updated to consider any conditional restrictions when resolving which restrictions need to be applied to a field.

Details

Dictionary

• Conditional Restrictions added to restrictions object type for all fields types (string/number/integer/boolean)
• Conditional Restriction match rules added:
  • codeList
  • count
  • exists
  • range
  • regex
  • value
• Reference replacement will now properly replace reference tags in:
  • recursively through nested meta objects
  • conditional restrictions, including nested recursive restrictions
  • codeList and regex match rules
• Formally removes script restrictions
• Moves unique restriction to be a property of a field, not part of restrictions
• Tests added:
  • recursive reference replacement
  • ensure conditional restrictions are parsed correctly by meta schemas

Validation

• Conditional restrictions are resolved based on value of fields in record
• Tests added:
  • conditional restriction test match rules
  • conditional restriction array case matching

Scripts

• JSON Schema generation script will now create a reference definition for field each field and each field's restriction types.
• New JSON Schema definition generated for the Lectern Dictionary, including conditional restriction types.

Github Issue Tracking

This accomplishes the majority of tasks listed in #209 .
The missing tasks will be moved into separate tickets to be completed separately:

• compare restriction
• compare conditional match rule
• condition arrayFieldCase to modify the rules for matching values in a field with an array of values.
