Scale relays without average or observed bandwidth.
Later it will be check what to do if their values are None or 0

since they are probably due a bug.

for each relay, calculate the filtered mean for all relays and
calculate the filtered ratio for each relay.

using timestamps class.
Also add one more result to the tests data and change the
test accordingly.

in RelayPrioritizer:
- Rename recent_priority_list_count to recent_priority_list when
  there is no counting
- Rename recent_priority_relay_count to recent_priority_relay
  when there is no counting
- Use the timestamps class to manage/count priority lists/relays

in RelayList:
- Rename recent_measurement_attempt_count to recent_measurement_attempt when
  there is no counting
- Use the timestamps class to manage/count measurement attempts

in RelayList:
- Rename consensus_timestamps to recent_consensus
- Rename recent_consensus_count to recent_consensus when there is
  no counting
- Use the timestamps class to manage/count consensuses
- Remove method not needed anymore

- Create new KeyValues constants for the new v1.5.0 KeyValues
- Instanciate State in Header.from_results so that there is no need
  to create new methods for all the header KeyValues that are read
  from the state file
- Add tor_version to the kwargs to initialize the Header
- Write tor_version in the state file when the scanner is started

Closes: #30196.

Replace HEADER_INIT_KEYS constant KeyValues with other constants
created in the previous commit.

- Add new KeyValues constants
- Remove HEADER_KEYS_V1X constant, only used once
- Replace HEADER_UNORDERED_KEYS with the new constants

After the automatic constants renaming, fix the flake8 errors by
reformatting automatically with `black`, only the lines that had
errors.

Part of #30196

Rename constants to make their names more consistent with each other.
All header constants start now by HEADER_ and all Bandwidth Lines by
BWLINE_.
The constants that are a list of keys are now named KEYS instead of
KEY_VALUE or KEY_VALUE.

These are the substitutions made:

s/BW_KEYVALUES_BASIC/BWLINE_KEYS_V0/

Fixes bug 30747; bugfix on 1.1.0.

Use bytes to compare the sum of scaled bandwidth (in KB) with the
sum of the consensus one (previously converted to Bytes measured.
Also:
- Check that the bandwidth attribute exists, since it was not
  stored in older versions.
- Do not sum the bw=1 as a result of the relays being unmeasured.
- Calculate the percentage difference as two difference values.
- Log which were actually the bandwidth sums.

It doesn't matter here because there're not operations with the
Keys and they're always converted to string in the bandwidth file,
but it less confusing as integer.

Also change list by int the methods that calculate the progress.

When the minimum percent of relays it's not reached, still report
the relays but set KeyValues accordingly so that Tor doesn't vote
on their bandwidth.
