yubikey-val/ykval-munin-vallatency.php
Jean Paul Galea 71442e7fd6 Refactor.
- don't depend on external binaries,
	it assumes too much and is dangerous.

- we can depend on libcurl instead,
	since it's already a dependency in core.

- we should do this for other plugins too,
	and move the new function into ykval-common.php

- plugin reports same exact values as before.
