feat(map): use targeting like syntax for configuration

No need to prefix some of them with underscore `_`.

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>`

## [2.0.4](https://github.com/saltstack-formulas/openssh-formula/compare/v2.0.3...v2.0.4) (2020-09-27)

### Bug Fixes

* **pillar:** `tofs` must not be under `mine_functions` ([c0d5052](c0d5052f6a))

### Tests

* **inspec:** `_mapdata` files should have `tofs` configuration ([5e9033f](5e9033f500))

fix(pillar): `tofs` must not be under `mine_functions`

The debug output of test jobs don't show the use of TOFS as it should
and the pillar.example show that `tofs` is under `mine_functions`
instead of `openssh`.

* pillar.example: move `tofs` under `openssh`.

* test/salt/pillar/default.sls: ditoo.

## [2.0.3](https://github.com/saltstack-formulas/openssh-formula/compare/v2.0.2...v2.0.3) (2020-09-09)

### Continuous Integration

* **kitchen:** force the hostname of the containers ([208f873](208f87380c))

### Tests

* **inspec:** no more need to mangle mapdata for hostname ([8cb31c6](8cb31c6967))
* **share:** standardise structure ([15241d3](15241d39c5))

test(inspec): use static hostname in mapdata

* Standardised using https://github.com/myii/ssf-formula/pull/251

We force the hostname in `kitchen` so the `_mapdata` files can be
static.

## [2.0.2](https://github.com/saltstack-formulas/openssh-formula/compare/v2.0.1...v2.0.2) (2020-08-26)

### Tests

* **inspec:** display proper diff when `_mapdata` mismatch ([1c99556](1c99556695))

test(inspec): display proper diff when `_mapdata` mismatch

The use of `eq` instead of `include` premits to have a nice diff after
the `expected/got` oneliners.

## [2.0.1](https://github.com/saltstack-formulas/openssh-formula/compare/v2.0.0...v2.0.1) (2020-08-21)

### Bug Fixes

* **map:** `path_join` can be used only for local file access ([3845d5f](3845d5ff61))

fix(map): `path_join` can be used only for local file access

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

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

# [2.0.0](https://github.com/saltstack-formulas/openssh-formula/compare/v1.3.1...v2.0.0) (2020-08-01)

### Features

* **map:** `config.get` lookups from configurable roots ([ad4385b](ad4385b077))
* **map:** update to v4 “map.jinja” ([df477b2](df477b25c2))

feat(map): update to v4 and add config.get lookup from multiple roots

BREAKING CHANGE: `map.jinja` has been upgraded from using `pillar.get`
to `config.get`.

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.
