It is possible that two descriptor upload requests are launched in a very
short time frame which can lead to the second request finishing before the
first one and where that first one will make the HSDir send back a 400
malformed descriptor leading to a warning.
To avoid such, cancel all active directory connections for the specific
descriptor we are about to upload.
Note that this race is still possible on the HSDir side which triggers a log
info to be printed out but that is fine.

When option validation or transition is happening, there are no
"current options" -- only "old options" and "maybe new options".
Looking at get_options() is likely a mistake, so have a nonfatal
assertion let us know if we do that.
Closes 22281.
Because we can get a RENDEZVOUS2 cell before the INTRODUCE_ACK, we need to
correctly handle the circuit purpose REND_JOINED that is not change its
purpose when we get an INTRODUCE_ACK and simply close the intro circuit
normally.

This test is important because it tests that upload_descriptor_to_all()
is in synch with pick_hsdir_v3(). That's not the case for the
reachability test which just compares the responsible hsdir sets.
There was a bug in upload_descriptor_to_all() where we picked between
first and second hsdir index based on which time segment we are. That's
not right and instead we should be uploading our two descriptors using a
different hsdir index every time. That is, upload first descriptor using
first hsdir index, and upload second descriptor using second hdsir index.
Also simplify stuff in pick_hdsir_v3() since that's only used to fetch
descriptors and hence we can just always use the fetch hsdir index.
Because of the latest changes on when we rotate, longer lifetime of
descriptors and no more overlap period, the tests needed to be improved to
test more functionnalities.

First, this fixes#23372.
Second, the consensus timings for the build descriptor have been changed to
the current test can pass. More extensive tests of descriptor rotation are
coming in a commit near you because the rotation and time period logic has
been changed.

This is a large and important unit test for the hidden service version
3! It tests the service reachability for a client using different
consensus timings and makes sure that the computed hashring is the same
on both side so it is actually reachable.

With the latest change on how we use the HSDir index, the client and service
need to pick their responsible HSDir differently that is depending on if they
are before or after a new time period.
The overlap mode is active function has been renamed for this and test added.
