Update required/recommended protocol versions.

Browse Source 
Cons=1 is the old format of consensuses, without ed25519 keys. It
  is no longer required or recommended.

  Cons=2 is the new format of consensuses, with ed25519 keys. It
  is now required.

  (Similarly for Desc=1,2 and Microdesc=1,2)

No supported client or relay versions should be affected by this
change, since these versions are supported by clients and relays
running 0.2.9 and later.  It will only take effect once enough
authorities vote for it.

Closes ticket 40162.

o Minor features (authorities):
- Authorities now list the directory formats used by currently supported
Tor releases as required. Previously, they listed only the formats
supported by older Tor releases as required. This change makes
the subprotocols "Cons=2 Desc=2 Microdesc=2" required, and makes
"Cons=1 Desc=1 Microdesc=1" no longer required or recommended.
Closes ticket 40162.
