disable the debian/ubuntu package version from being sent to clients
dkg pointed out to riseup that our ssh servers were revealing the package version to clients, which is controlled by the DebianBanner config option. It exists in both Debian and Ubuntu and defaults to 'yes', so we explicitly set it to 'no' in the templates for those distros.

choose better MAC for squeeze and wheezy
both squeeze (1:5.5p1-6+squeeze6) and wheezy (1:6.0p1-4+deb7u2) have MACs better than hmac-sha1 available in the default search, they both have hmac-sha2-512, hmac-sha2-256, and hmac-ripemd160. So switch to using hmac-sha2-512, which lets us lock down the client MACs more.

sync LoginGraceTime with debian defaults
for some reason this was 10 minutes in our module, yet 120s everywhere else.
and only in wheezy too, wtf...

add override_builtin parameter to handle the common authorized_key directory case
riseup uses a common authorized_keys directory and this commit works around a bug in the puppet function that can't handle that. See the longer comment in the code.
See merge request !15
Some people might want to inject their own logic before including nagios
resources. We can explain that since the nagios resources are in their
own part of the manifests, they can shortcut the module's automatic
handling of it, and call it manually from their own manifests.
Fix for Debian squeeze and ssh_keygen for Puppet < 3 installs
Facter versions that are shipping in Debian squeeze and wheezy do not support the operatingsystemmajrelease core fact, which appears only from facter 1.7 onwards.
This isn't a big problem for wheezy since the openssh-server version it ships supports multiple AuthorizedKeysFile file paths,
On Debian squeeze, openssh-server does NOT support multuple AuthorizedKeysFile and will refuse to start with such a definition.
ALSO:
`ssh_keygen` is currently broken for Puppet 2.7.x clients. This commit should resolve the issue.
The fix was suggested by @ng in reference to https://github.com/duritong/puppet-sysctl/blob/master/lib/puppet/provider/sysctl_runtime/sysctl_runtime.rb#L16-L17

types you want to support in your sshd_config.
We use the ssh_version fact to determine the default hostkey types.
Only enable rsa and ed25519 for ssh versions greater or equal
to 6.5, otherwise enable rsa and dsa.
Some distributions, such as debian, also enable ecdsa as a hostkey
type, but this is a known bad NIST curve, so we do not enable that
by default (thus deviating from the stock sshd config)
