The `config_get_lookup` and `config_get` sources lack flexibility.

It's not easy to query several pillars and/or grains keys with the
actual system. And the query method is forced to `config.get` without
being configurable by the user.

We define a mechanism to select `map.jinja` sources with similar
notation as the salt targeting system.

The `map.jinja` file uses several sources where to lookup parameter
values. The list of sources can be modified by two files:

1. a global salt://parameters/map_jinja.yaml
2. a per formula salt://{{ tplroot }}/parameters/map_jinja.yaml.

Each source definition has the form `<TYPE>:<OPTION>@<KEY>` where
`<TYPE>` can be one of:

- `Y` to load values from YAML files, this is the default when no type
  is defined
- `C` to lookup values with `config.get`
- `G` to lookup values with `grains.get`
- `I` to lookup values with `pillar.get`

The YAML type option can define the query method to lookup the key
value to build the file name:

- `C` to query with `config.get`, this is the default when to query
  method is defined
- `G` to query with `grains.get`
- `I` to query with `pillar.get`

The `C`, `G` or `I` types can define the `SUB` option to store values
in the sub key `mapdata.<key>` instead of directly in `mapdata`.

Finally, the `<KEY>` describe what to lookup to either build the YAML
filename or gather values using one of the query method.

BREAKING CHANGE: the configuration `map_jinja:sources` is only
                 configurable with `salt://parameters/map_jinja.yaml`
		 and `salt://{{ tplroot }}/parameters/map_jinja.yaml`

BREAKING CHANGE: the `map_jinja:config_get_roots` is replaced by
                 compound like `map_jinja:sources`

BREAKING CHANGE: the two `config_get_lookup` and `config_get` are
                 replaced by `C@<tplroot>:lookup` and `C@<tplroot>`
		 sources

On windows machines, the `path_join` build wrong URL by using
backslash as separator.

URL used for fileserver access must use only slashes `/`.

We avoid compatibility break with user pillars by looking up
configuration values using `config.get` in configurable roots.

We provide a new parameter `map_jinja:config_get_roots` in the formula
`parameters/defaults.yaml`to retrives values not only from
`tplroot=openssh` but from `sshd_config` and `ssh_config` too.

We need to update the `_mapdata` reference files to include the new
`map_jinja:config_get_roots`.

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.

```bash
Examining openssh/map.jinja of type state
[209] Jinja comment should have spaces before and after: {# comment #}
openssh/map.jinja:4
{## Start imports as  ##}

[209] Jinja comment should have spaces before and after: {# comment #}
openssh/map.jinja:19
{## merge the openssh pillar ##}
```

* Add map for debian

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

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

This state manages /etc/ssh/ssh_known_hosts and fills it with
public SSH host keys of other minions.
