BridgeAuth should add a `published` line to bridge networkstatus documents
While hacking on getting BridgeDB to use Stem's descriptor parsers, I noticed that @type bridge-network-status 1.0
documents do not have a published
line, like other networkstatus documents. I proposed that a new @type bridge-network-status 1.1
descriptor type is created, where Bridge Authorities add a published
line to the head of the document.
