Description of the problem:
After spoke cluster is installed on hypershift  and imported via UI, 0 nodes are reported as part of the cluster. 

In infrastructure tab I can see 3 nodes are installed and are part of the cluster.

In machine-approver-controller log I can see errors "failed to get kubelet CA: ConfigMap "csr-controller-ca" not found".

in hypershift operator log

How reproducible:

tried 2 times - the same result

Steps to reproduce:

1. Deploy hypershift with 3 masters

2. Deploy spoke cluster with 3 workers

3. Using UI Import the cluster 

4. Ensure IP for application is set correctly in /etc/NetworkManager/dnsmasq.d/openshift.conf on hypervisor (the correct IP can be found by running $oc get pods -n openshift-ingress -o wide on spoke). Restart NetworkManager if the IP was changed

Actual results:

0 nodes (see in problem description)

Expected results:
Spoke cluster is Ready and 3 workers are attached to it
