We use the oldest-circ-first method here, since that seems good for conflux:
queues could briefly spike, but the bad case is if they are maliciously
bloated to stick around for a long time.
The tradeoff here is that it is possible to kill old circuits on a relay
quickly, but that has always been the case with this algorithm choice.

This adds 2 histogram metrics for hidden services:
* `tor_hs_rend_circ_build_time` - the rendezvous circuit build time in milliseconds
* `tor_hs_intro_circ_build_time` - the introduction circuit build time in milliseconds
The text representation representation of the new metrics looks like this:
```
# HELP tor_hs_rend_circ_build_time The rendezvous circuit build time in milliseconds
# TYPE tor_hs_rend_circ_build_time histogram
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="1000.00"} 2
tor_hs_rend_circ_build_time_bucket{onion="<elided>",le="5000.00"} 10

This adds a `reason` label to the `hs_intro_rejected_intro_req_count` and
`hs_rdv_error_count` metrics introduced in #40755.
Metric look up and intialization is now more a bit more involved. This may be
fine for now, but it will become unwieldy if/when we add more labels (and as
such will need to be refactored).
Also, in the future, we may want to introduce finer grained `reason` labels.
For example, the `invalid_introduce2` label actually covers multiple types of
errors that can happen during the processing of an INTRODUCE2 cell (such as
cell parse errors, replays, decryption errors).

This introduces a couple of new service side metrics:
* `hs_intro_rejected_intro_req_count`, which counts the number of introduction
requests rejected by the hidden service
* `hs_rdv_error_count`, which counts the number of rendezvous errors as seen by
the hidden service (this number includes the number of circuit establishment
failures, failed retries, end-to-end circuit setup failures)
Closes#40755. This partially addresses #40717.

Directory authorities now include their AuthDirMaxServersPerAddr
config option in the consensus parameter section of their vote. Now
external tools can better predict how they will behave.
In particular, the value should make its way to the
https://consensus-health.torproject.org/#consensusparams page.
Once enough dir auths vote this param, they should also compute a
consensus value for it in the consensus document. Nothing uses this
consensus value yet, but we could imagine having dir auths consult it
in the future.
Implements ticket 40753.
This updates the docs to stop suggesting `pk` can be NULL, as that doesn't seem
to be the case anymore (`tor_assert(pk)`).

When I copied this to arti, I messed up and thought that the default
time period was 1440 seconds for some weird testing reason. That led
to confusion.
This commit adds a test case that time period 1440 is May 20, 1973:
now arti and c tor match!
