ACR Integration not working due to basic-auth authentication

Describe the bug
Authenticating to ACR is not working, see the logs below. very likely due to attempting to authenticate to acr directly through basic-auth instead implementing an oauth2 authentication flow.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Registries'
2. Click on 'Add registry'
3. Add an ACR registry with a valid ACR account
4. Try to sync and scan the registry
5. See error above

Expected behavior
It should succeed and be able to authenticate and scan the repositories.
And even in case of a failure, I would expect something to appear on the front-end.
