Add a CLI compatible Rust implementation of pvattest-C. - All (non-experimental) options are supported and work exactly as in the C implementation. For some options/parameters new variants are available. - `perform` now also accepts positional arguments, while keep accepting -i and -o that was mandatory in the C implementation. - `version` may also be a command instead of an option now. - -V is deprecated - -v increases verbosity instead of showing the version - all experimental options are dropped Acked-by: Qi Feng Huo <huoqif@cn.ibm.com> Acked-by: Marc Hartmayer <mhartmay@linux.ibm.com> Signed-off-by: Steffen Eiden <seiden@linux.ibm.com>
