Multiline EC private and public keys are causing systemd services to fail during cluster installations. While this issue does not result in a complete cluster failure, it generates warnings in the `journalctl` logs, which could confuse users when diagnosing installation issues. The root cause is systemd's inability to properly parse multiline keys, leading to service crashes and unnecessary log noise. This should be addressed to improve the clarity of logs and prevent misleading warnings during the cluster setup process.

    Always

    1. Create a 4.16 cluster using ABI
    2. Observ the journaltctl logs
    3. You will see warning/errors mentioning the EC keys(EC_PUBLIC_KEY_PEM) are not parsed correctly
    

Parsing errors related to EC keys    

    1. No parsing errors related to EC keys. Example: agent-register-infraenv.service: Ignoring invalid environment assignment
     2. No multiline public key in /usr/local/share/assisted-service/assisted-service.env.  Public key should be base64 encoded
