      summary: Onboard a TPP with a given LFI
      description: >-
        Allows a TPP to onboard with a given LFI. This is a one-off operation
        that is invoked the first time a TPP accesses the LFI.


        An empty request body is submitted to the operation. The OFP will
        introspect the TPP client certificate to extract the TPP ID, and use
        this to complete onboarding at the Trust Framework.


        Once the operation is complete the TPP will be able to call the LFI
        APIs.
