    Support signing server descriptors
    
    Fuck yeah, got it! Signing server descriptors we create.
    
    Leekspin uses PyCrypto which is deprecated [1], so wasn't able to take
    advantage of it as much as I hoped. On the upside cryptography is simpler than
    what Isis had.
    
    There was one rough bit though - cryptography embeds a constant indicating the
    hashing algorithm it signs with. This required us to hack out part of its
    internals. Hopefully upstream is amenable to adding a flag for this.
    
    Thus far we only sign server descriptors. Gonna follow this up with other
    descriptor types Leekspin supports so we can migrate BridgeDB's tests to use
    this.
