Include content of client_ca.crt and client_ca.key in hiera

i'm reorganizing the deployment of x509 material (see parent task), and noticed that most x509 content is included in hiera, but the client_ca crt+key is only referenced as a filename:

  ...
  client_ca_cert: /etc/leap/files/ca/client_ca.crt
  client_ca_key: /etc/leap/files/ca/client_ca.key
  ...

i would like deploy all x509 stuff with the x509 puppet module so we have it at one place. Is there any reason why the client_ca content is not included in hiera ? Can we change that ?
