WIP: Reject bridge descriptors posted to non-bridge authorities
Right now if my bridge descriptor gets uploaded to the directory authorities, poof I'm now a public relay, even if I didn't mean to be.
That's not the end of the world, since I am technically offering to be a relay already, and the only difference is that I didn't opt to publish my descriptor myself.
But still it seems like we should make the choice explicit inside the descriptor.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
