to show the number of times a relay receives these events while being
measured and diagnose bottlenecks at bwauths.

This is part of the optimizations for #40130.

This is part of the optimizations for #40130

when the consensus parameter `bwscanner` is 2.

"Using upload instead of download allows the congestion control
algorithms to be under control of the sbws Tor client, instead of the
Exit relay. This means that sbws can know when `slow start` has exited."

This is the 1st optimization for #40130

.

The testing HTTP server has been replaced by the one implemented in
onbasca just cause a first try on implementing `do_POST` was
successful only for the 1st sbws request. It only implemnts POST RFC
2388.

So that the `resultdump` threat can continue even if there's an
exception and the operator gets notified about the error.

There is no need to restart sbws after solving the filesystem issue
that caused the exception.

Close #40143

past to method `only_relays_with_bandwidth` and it's declaration was
recently changed.
Also fix typo.

Closes #40137

before selecting other exits as helpers.
In #40136 we forgot to consider the corner case in #40041, discovered
thanks to analysis#36.
This was causing that sometimes a CC circuit was built when
bwscanner_cc wasn't equal or greater than 1 or the other way around.

We didn't realize about this cause this part of the code is very
confusing. To don't make it even more confusing, i've changed the
internal API:
- `select_helper_candidates`: split funtion into one to select the
  helper candidates, knowing whether to use the relay as exit or not
  and other function `use_relay_as_entry` to decide whether to use the
  relay as entry or not checking CC params.
  Also pass a new arg `relay_as_entry`.
- `create_path_relay`: rewmove not used `cb` arg, add `candidates` arg
  to stop having to select them again later on. Move the no
  `candidates` condition here instead of checking it in
  `pick_ideal_second_hop`.
- `_pick_ideal_second_hope: remove unneded `dest` and `cont arguments,
  rename `is_exit` to `helper_is_exit`. Use the candidates instead of
  selecting them again.
- `measure_relay`: in the case an exit fails to exit, select the
  candidates knowing that they have to be exits and checking CC.
- `only_relays_with_bandwidth`: remove unneded arg `controller` so
  that there is no need to pass it through several functions.

Update changelog and change release milestone in CI.

Closes #40118.

that was long ago released

Remove comment about tor 0.3.5, already EOL and update dates other tor
releases become stable or EOL.
No need to remove tests with tor 0.3.5, since there wasn't anymore.

Also:
- add Python 3.10 as supported version.
- target Python 3.10 in black

because it's already EOL. Also update dates other python releases.

Also:
- remove redundant image variable
- build docs with python 3.9 too
- Add python 3.9 as target-version for black

if both operands are simple. To make CI tests pass with new black
version 22.1 (#2726).

Closes #40123

If a bwauth operator wish to receive (email) alerts, it might be more
convenient to set the log level to error.
