Delay loading the attestation data immediately, and only compute it upon
request. We do this using a deferred function which allows to define the
computation in the same place as before, but perform the computation
later.
With this patch, we ensure that the attestation data is only pulled from
the remote if it is actually referenced in the format string -
otherwise, we can skip it, for improved performance.
