[pve-devel] [RFC PATCH v2 common] Use double hyphens when prefixing command options in the documentation

This makes our man pages follow the GNU long option recommandations
where non-single character options are prefixed with a double hyphen
(https://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html)

The benefit for PVE is that our documentation looks more similar to what
a user with previous Linux knowledge is used to.

Our bash autocompletion helper only completes options using double hyphens too.
