Fix tor warnings that chutney is currently ignoring

Chutney ignores a large number of common tor warnings in order to produce readable output from its warnings.sh script: https://gitweb.torproject.org/chutney.git/tree/tools/ignore.warnings

Some of these warnings have individual tickets (I'll parent them to this task).

Of the remainder, we can probably remove the tor warnings for:

• expands into rules which apply to all private IPv4 and IPv6 addresses

If we fixed consensus failures in chutney networks, we'd eliminate most of the rest, but there's a tradeoff here with bootstrap speed.

Some of the rest might be able to be fixed using chutney config changes.

And others are ok: Some are expected every time tor is freshly launched. Others are expected every time tor is running in a test network.
