Make Publickey authentication configurable

[debbabi]

Description

PubkeyAuthentication is actually hardcoded as true.
We have some cases in our cluster were we want to set it to false globally, but true for some Matched Addresses only (using Match Address directive) like the following configuration example:

# /etc/ssh/sshd_config
...
PubkeyAuthentication no
...
Match Address 192.168.1.0/24
    PubkeyAuthentication yes
...

Solution

Add a new variable ssh_pubkey_authentication and set it true by default.
As like, we can override this global default value to false and set our specific Match Address rules.
