keyless signing

[migmartri]

This documentation on how to configure keyless signing seems obsolete

It needs to go from

controlplane:
  keylessSigning:
    enabled: true
    backends: 
      - fileCA:
          cert: |
            -----BEGIN CERTIFICATE-----
            ...
            -----END CERTIFICATE-----
          key: |
            -----BEGIN ENCRYPTED PRIVATE KEY-----    
            ...
            -----END ENCRYPTED PRIVATE KEY-----
          keyPass: "REDACTED"  

to

controlplane:
  keylessSigning:
    enabled: true
    backends: 
      - issuer: true
        type: fileCA
        fileCA:
          cert: |
            -----BEGIN CERTIFICATE-----
            ...
            -----END CERTIFICATE-----
          key: |
            -----BEGIN ENCRYPTED PRIVATE KEY-----    
            ...
            -----END ENCRYPTED PRIVATE KEY-----
          keyPass: "REDACTED"  

it was missing issuer and type
