[tor-relays] BWauth no-consensus state in effect

Description

At present both 'longclaw' and 'maatuska' have
dropped out of the BW consensus ('longclaw'
is restarting with new version, not sure
about 'maatuska').

This has caused the BW consensus logic to revert
to using relay self-measurement for BW weightings
due to fewer than three BW authorities participating.

The 10000 cap placed on self-measure values
is causing super-fast relays serious demotion
and slower relays corresponding promotion
in the consensus weighting.

Possibly this may result in network
unbalance issues. Some adjustment
of the logic seems in order.
