Dropped leftover debugging output

The code uses 'public_ssh_hostname' and not 'public_ssh_host_names'.

(which also happend to break Python 3 compatibility.)

Allow removing keys based on source file.

Fix fetching default ssh_config.

Closes #153.

CentOS does not support ed25519; fixes #98

* ssh_config: properly render host options (fixes #145)

* ssh_config: whitespace optimization (fixes #145)

Config backup option

Added Debian sftp subystem

added possibility to configure server version and client version
with pillar example

The `ssh_config` state supports generating `Host` sections, but it is
buried in the source. By default, options are simply dumped in the
configuration file; without any `Host` directive.

This patch hints (and, actually, encourages) users to use `Host`
sections by updating the pillar example to use the `Hosts` directive
with the `*` pattern.

Fix invalid require_in sshd_config for key states

Change the require_ins used by the key management states in the
config.sls to be conditional based on whether the sshd_config
is managed by the formula

Fixes #130

* Pillar openssh.known_hosts_salt_ssh

* Dropped ill-named file

* Fixed aliasing of host names

* Improved pillar.example

* Opt-in to include localhost

* pillar/known_hosts_salt_ssh: clear cache in run()

* Dropped forgotten debugging output

Add host keys from pillar to `ssh_known_hosts`

* Add map for debian

Add latest changes from upstream

[openssh/config_ini] initial version of config_ini which uses ini state

fix iteritems for python3

closes #123

[FIX] When key is present override generating by any way

* drop default values (fixes #102)
* hmac-ripemd160 was dropped in 7.6

Add ConfigBanner to processed_options when handled.

Hostnames in known hosts

This prevents a verbatim version being added to end of file that will
cause the parsing to fail.

Fixed supporting multiline banner_string defined in the pillar.
