This ticket is to investigate why import-applications task fails sometimes with DNS lookup error on PSI cluster after applying the cf-deployment/update-psi-cluster-nodes-hosts.sh script

Steps to reproduce:

In the Administration perspective:
1. Create a source control credential for CF instance
2. Create a source platform using the CF API URL: https://api.bosh-lite.com and attach creds
3. Click the right kebab menu of the source platform and select Discover applications
4. Filter by organization `org` and submit the task

The task fails:

errors:
    - severity: Error
      description: 'Container (addon) failed: Error'
    - severity: Error
      description: 'error while discovering token service URL: error executing request, failed during HTTP request send: Get "https://api.bosh-lite.com/": dial tcp: lookup api.bosh-lite.com on 172.30.0.10:53: server misbehaving'
