What would you like Teleport to do?
When creating a new AWS OIDC Integration, if something is not correctly set up, the user must be warned about it.

What problem does this solve?
If the integration is not correctly set up, users are only aware of it much later, when using a specific feature.
Eg, when the cluster is not publicly accessible, the user sets up the integration and only finds out that it is not working when they try to use any feature that depends on it (eg, auto-enroll ec2 instances)

If a workaround exists, please include it.
