OctoRPKI does not limit the length of a connection, allowing for a
slowloris DOS attack to take place which makes OctoRPKI wait forever.
Specifically, the repository that OctoRPKI sends HTTP requests to will keep
the connection open for a day before a response is returned, but does keep
drip feeding new bytes to keep the connection alive.
