SchemaMappingTransform allow kinds to be defined

The addition of SchemaMappingTransform is wonderful however it will always return a string.

There are some reasons why you might not want to return a string. Such as in IP Fabrics case we display an interface state as up or down. But I need to be able to convert it to a boolean for a generic InfrahubSchema to be useful to anyone.

Interface Schema:

attributes:
  - name: enabled
     kind: Boolean

Sync Config

  - name: InfraInterface
    transforms:
       - field: l1
          expression: '{{ "true" if "up" in l1 else "false" }}'
    mapping: ...
    fields:
      - name: enabled
        mapping: l1

Returning a string will fail as enabled expects a Boolean. If there was a way to define the kind in the transforms like so:

  - name: InfraInterface
    transforms:
       - field: l1
          expression: '{{ "true" if "up" in l1 else "false" }}'
          kind: Boolean
    mapping: ...
    fields:
      - name: enabled
        mapping: l1

Then it would be good to convert the string to another type allowing yes/no or true false, if kind is Number then it converts the string to an int if its valid for the infrahub schema.

After speaking about this with the Infrahub Team it makes sense to not have a kind and derive the kind from the destination schema.
