Add the upload-only option to the Horizon patch orchestration UI

This change adds the new DC patch orchestration upload-only option to
the patch orchestration UI. A new 'Upload Only' checkbox was added to
the 'Create Strategy' form when the selected strategy type is 'Patch'.

In the 'Orchestration Strategy' tab, if the current strategy is a patch
strategy, a new field 'Upload Only' with its current value is now shown
so that the user can know if an existing strategy is using this option.

Test Plan:
1. PASS - Verify that the 'Upload Only' checkbox appears correctly
          inside of the create strategy form only when the selected
          strategy type is equal to 'Patch';
2. PASS - Create a patch strategy with and without the upload-only
          option and verify that it gets created successfully;
3. PASS - Verify that the interface shows the 'Upload Only' field and
          its current value on the 'Orchestration Strategy' page only
          when using the patch strategy type;
4. PASS - Create and delete another orchestration type (e.g. Kubernetes
          upgrade) through Horizon and verify that it still works as
          expected;
5. PASS - Run the entire patch orchestration procedure through Horizon
          and verify that it completes successfully.
