[torspec/master] prop224: Change how descriptor encode encryption keys

commit 3f9333044e77759996083d0d9dd2c8053358d895 Author: David Goulet <dgoulet(a)torproject.org> Date: Thu Apr 6 08:29:20 2017 -0400 prop224: Change how descriptor encode encryption keys Every intro point, legacy or not, needs a ntor encryption key. However, in the case of a legacy introductin point, we need an extra RSA key so the IP can relay the INTRODUCE1 cell on the right circuit. We now only need the cross certificate for the encryption key because the signing-key extention make sure we have the actual key encoded in that certificate. The legacy key cross certificate doesn't support that extention so we need both the RSA key and the crosscert.
