openssh.config_ini / HostKey clobbering

[jtryon]

While testing the ini style config formula I've found that it clobbers the 4 default HostKey in the Ubuntu sshd_config down to the last one (without a HostKey specified in the pillar).

sshd_config Before

HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

sshd_config After

HostKey /etc/ssh/ssh_host_ed25519_key

Following the pillar.example style of HostKey config Salt fails to compile the SLS on the minion. I think that's just because the current pillar.example isn't made with the config_ini formula in mind (it has a list/block of hostkeys which causes the compile issue).

All the other config variables which only appear once aren't affected and update just fine.

@jtryon Thanks for your bug report.
The config_ini.sls variant is AFAIK developed independently of the "normal" config.sls. Furthermore I'm not sure whether config_ini.sls receives as much attention as config.sls.
Could you please submit a PR which fixes the issue?
