Supports enhancement to prevent resolution with file array based model validation

[digimaun]

• Prevent resolution with file array based model validation. If a dependent model is not available in the array a resolution failure will occur. Covers issue https://github.com/Azure/iot-plugandplay-models-tools/issues/134.
  • Pipeline change: Observed possible deadlock in the runner environment when running mixed framework tests in a single job. The change splits target framework tests into unique jobs and makes a couple other test config changes to prevent issues.
  • Overall notable reduced test time for the CLI.
  • Will keep an eye on it.
