Moritz Halbritter 02a49b6038 Add a MeterBinder for SSL chain expiry
It registers a 'ssl.chains' gauge to count the number of chains with
different statuses (valid, expired, not yet valid, will expire soon).

Additionally, it registers a 'ssl.chain.expiry' gauge for every
certificate in a chain, tracking the seconds until expiry.

This binder reacts on bundle updates and new bundle registrations.
