e7abab8782 relay: For metrics, don't report DNS errors by query type
This is due to the libevent bug
https://github.com/libevent/libevent/issues/1219 that fails to return
back the DNS record type on error.

And so, the MetricsPort now only reports the errors as a global counter
and not a per record type.

Closes #40490

7a8108ea87 relay: Overload state on DNS timeout is now X% over Y secs
With this commit, we will only report a general overload state if we've
seen more than X% of DNS timeout errors over Y seconds. Previous
behavior was to report when a single timeout occured which is really too
small of a threshold.

The value X is a consensus parameters called
"overload_dns_timeout_scale_percent" which is a scaled percentage
(factor of 1000) so we can represent decimal points for X like 0.5% for
instance. Its default is 1000 which ends up being 1%.

The value Y is a consensus parameters called
"overload_dns_timeout_period_secs" which is the time period for which
will gather DNS errors and once over, we assess if that X% has been
reached ultimately triggering a general overload signal.

d455f9e18a hs: v2 address are now considered a bad hostname
This means that at this commit, tor will stop logging that v2 is
deprecated and treat a v2 address as a bad hostname that we can't use.

15ede0435f Lower maximum value for guard-extreme-restriction-percent to 100.
Values greater than 100 would have had the same effect as 100, so
this doesn't actually change Tor's behavior; it just makes the
intent clearer.  Fixes #40486; see also torspec#66.
