Description of problem:

Right now, when entering a misconfiguration in the servingruntime spec for a Model Server creation, will only log an error in the console and fallback to the default configuration.

Prerequisites (if any, like setup, operators/versions):

Have rhods 1.21 installed

Steps to Reproduce

1. Modify the servingruntimes-config configmap with wrong configuration 
2. Create a new model server
3. Check that the modal will submit the action and a error is logged

Actual results:

The modal won't alert the user that is using the default configuration

Expected results:

The modal should have an indicator about the failing state of the servingruntime spec.

Reproducibility (Always/Intermittent/Only Once):

Always

Testing steps

1. Delete the `servingruntimes-config` ConfigMap
2. Create a new Model Server
3. The new model deploy should have the fallback image
4. Create again the configmap with malformed values
5. Try to create a new Model Server
6. It will fail displaying a new message.
