help: hide command line options marked as "advanced"

Previously, we have keywords like "(DEPRECATED)" and "(EXPERIMENTAL)" to
hide command line options in non-verbose help output.

However, sometimes an option is neither deprecated nor experimental. It's
well-tested and working, but just not designed to average users. This patch
adds a keyword "(ADVANCED)" to fit in such use cases.

Thanks rom1dep for the suggestion of the word "advanced".
