Model Registry: Get latest Semantic Version

Fred de Gier requested to merge 428644-resolve-latest-version-based-on-semver into master

What does this MR do and why?

This MR changes the behavior of the endpoint ml/get_latest_versions it now returns the highest / latest Semantic Version instead of the highest ID. Allowing users to provide beta releases, patch versions for older models, etc while still pointing to the latest / highest released version.

  2. Create model if one doesn't exist, give it a model name and version (1.0.0, click Create
  3. Create another model version for the same model with a lower server e.g. 0.0.1
  4. Perform the following cURL
