[netconf] ietf-ssh-server host key

[Michal Vasko <[e-mail]>]

Hello,

we are implementing these modules (ietf-netconf-server and imports) and 
I have a question regarding the container 
`/ietf-netconf-server:netconf-server/listen/endpoint/ssh/ssh-server-parameters/server-identity/host-key/public-key`. 
It looks like this

+--rw public-key
    +--rw (inline-or-keystore)
       +--:(inline) {inline-definitions-supported}?
       |  +--rw inline-definition
       |     +--rw public-key-format     identityref
       |     +--rw public-key            binary
       |     +--rw private-key-format?   identityref
       |     +--rw (private-key-type)
       |        +--:(cleartext-private-key) {cleartext-private-keys}?
       |        |  +--rw cleartext-private-key?   binary
       |        +--:(hidden-private-key) {hidden-private-keys}?
       |        |  +--rw hidden-private-key?   empty
       |        +--:(encrypted-private-key) {encrypted-private-keys}?
       |           +--rw encrypted-private-key
       |              +--rw encrypted-by
       |              +--rw encrypted-value-format    identityref
       |              +--rw encrypted-value           binary
       +--:(keystore) {central-keystore-supported,asymmetric-keys}?
          +--rw keystore-reference?   ks:asymmetric-key-ref

What is there the public key for? For a key to be used as a host key you 
only need the private key (technically, you can always generate the 
public key from the private key but the public key is not needed at all 
in this case) and it is causing us some problems because it is even 
required to be in the `ssh-public-key-format` without any information as 
to why. Thanks for any explanation.

Regards,
Michal
