List writeable/readable data (Roman's DISCUSS)

[boucadair]

** Section 8. Per the guidance on writeable data, aren’t significant parts of
alto-server/listen sensitive as one could alter the stored keys for the server
or client; or the username/password combinations (in http-server-parameters)?

** Section 8. Per the guidance about readable data:

-- isn’t tls-server-parameters sensitive since it could contain raw private
keys (e.g., ks:inline-or-keystore-symmetric-key-grouping)?

-- Would it be best practice to be able to read all of the authorized users?
