Jeroen de Borst 833979f7b8 Adding metrics for hostname candidate use.
These metrics by themselves won't be as useful, unless they can be correlated to the use of the
feature 'WebRtcHideLocalIpsWithMdns'. This can be done by running a finch experiment where we turn
the feature on for a % of users, we can then compare these metrics for users with and without
the feature turned on.

A complementary change is required in Chrome:
