Tdl 17961 poc on rule map implementation

[prijendev]

Description of change

• Created RuleMap class which contain following below method,

  • fill_rule_map_object_by_catalog
  • apply_ruleset_on_schema
  • apply_ruleset_on_stream_name
  • apply_rules_to_original_field
  • apply_ruleset_on_api_response

• Added extra method add_child_into_metadata to add nested fields into metadata.

• The catalog contains the original-name field in metadata which contains the actual name field and the breadcrumb contains the standard name of the field.

• During sync mode, apply_ruleset_on_api_response would be called which converts the original field value to standard name, and then the transform would be applied.
