The `map.jinja` now exports a single variable called `mapdata`.

We extract the `openssh`, `sshd_config` and `ssh_config` from it to
minimize the changes to `.sls` files.

* Close #165
* Move existing `.kitchen.yml` => `kitchen.vagrant.yml`
* Semi-automated using https://github.com/myii/ssf-formula/pull/30
* Fix errors shown below:

* Use consistent Jinja whitespace control `{%- ... -}`
* Improve debug output (comments & whitespace control)
* Use exact state names with TOFS `files_switch`
* Add `ssh_known_hosts_src` to `defaults` (for consistency)
* Restrict `pillar.example` changes to TOFS only
* Use `fire_banner` in `pillar.example` to indicate available template

This set of options reflect the ssh_config options that are set by
default on Debian. The way this was set before has the potential to
break exisisting setups that rely on "normal" defaults, rather than the
rather opinionated ones that are now being shipped with this formula.

put the ssh_config Host:* options in the defaults file so they can be overridden

Made a small change to reflect the default sshd_config

Added defaults.yaml and map.jinja similar to template-formula and salt-formula
