d0be2ae7f9 Extend get_voting_interval() so that it's callable by relays. 
In the past, only authorities and clients had to use that function because of
the SRV subsystem. However, because of its use in rep_hist_hs_stats_init() it
will now also be used by relays when bootstrapping without a consensus. Make it
do something sensible.

Another approach (instead of using magic values) would be to wait
initialization of HSv3 stats until we get a consensus but that seems messy to
schedule.

Another approach would be to make dirauth_sched_get_configured_interval() also
work for relays (particularly when TestingNetwork is enabled), but that also
seems a good amount of work.

362229f184 lib/metrics: Fix wrong macro expansion 
The "METRICS_PREFIX" was not expanded but rather used as a litteral. Fix that
by just removing the define and using "tor_" directly.

50f44afeb4 hs: New metrics module 
At this commit, a new service registers to the module and a store is created.
It also remove itself from the metrics module if it goes away.

In order to hook into the metrics subsystem, this commit attaches the HS
subsystem into the subsystem global list so its get_metrics() call can be
accessible.

HS initialization is still _not_ done through the subsys module as it is
likely require much more testing.
