information needed to for V2 authentication. Also moved 
authenticator creation out of ConnectionToHost.

-// method names.
-// Currently the following methods are supported:
-//   v1_token - deprecated V1 authentication mechanism,
-//   spake2_plain - SPAKE2 without hashing applied to the password.
-//   spake2_hmac - SPAKE2 with HMAC hashing of the password.
