1. Proposed title of this feature request

Instantiation of templates gives no positive (on success) or negative (on instantiation failure) feedback to user

2. What is the nature and description of the request?

When creating a custom or existing DevConsole Template, it handles no errors or success states. It always takes you to the Topology page, success or failure.

3. Why does the customer need this? (List the business requirements here)

Logged as a BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1876535

No errors in the UI and thus no way to debug what has happened and why the template was not instantiated.

4. List any affected packages or components.
