Other tools may need to process the configuration-unique id. Provide a
machine readable format by writing to a YAML file containing a `cuid`
entry and optionally an `add` entry. New CLI options `--format` and
`--output` are introduced for this. Currently, only the output format
`yaml` is supported.

pvattest is a tool to attest an IBM Secure Execution guest.
In a trusted environment, one can create a request using
`pvattest create`. To get a measurement of an untrusted
IBM Secure Execution guest call 'pvattest perform'.
Again in a trusted environment, call 'pvattest verify'
to verify that the measurement is the expected one.
The tool runs on s390 and x86.
It has the same requirements like libpv and therefore
requires openssl v1.1.1+, glib2.56+, and libcurl.
Additionally, to measure, the linux kernel must provide
the Ultravisor userspace interface `uvdevice` at /dev/uv
and must be executed on an IBM Secure Execution guest on
hardware with Ultravisor attestation support, like IBM z16 or later.
