Support for Credentials

[rdbartram]

Summary of the new feature / enhancement

In order to be able to call certain types of resources, credential objects are required. I would be very useful to have an intuitive way to do this.

# example.dsc.config.yaml
$schema: https://raw.githubusercontent.com/PowerShell/DSC/main/schemas/2023/10/config/document.json
resources:
  - name: Get info from classic DSC resources
    type: DSC/PowerShellGroup
    properties:
      resources:
      - name: Get Teams App Permission Policy
        type: Microsoft365DSC/MSFT_TeamsAppPermissionPolicy
        properties:
          Identity: Global
          Credential:
            userName: "[email protected]"
            Password: "MyPassword"

Being able to define and then reference would be great but maybe some interp. from dsc exec itself to get values from environment or a secret manager would be great too
