[tor-commits] [onionoo/master] Fix how we're processing exit lists.
commit e630a086cf900918cf18a26f181f2b93fe7f033b
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

Fix how we're processing exit lists.
This commit really contains three fixes:
1. We were previously processing exit lists when writing details
documents. That had the downside that we only included exit addresses
when we parsed new exit lists. Now we're storing exit list entries
together with the scan time in details statuses and include them in
details documents until they are older than 24 hours.
2. We now make sure that the latest exit addresses make it into node
statuses and are not reset when there is no exit list to parse. This
fix is pretty similar to 0dc7436.
3. We now clarify in the specification that the `search` parameter
includes exit addresses.
Altogether, fixes #11066.
