Support complex compound matches in Match criteria. For example, be able
to match against multiple Users for a given Match, or be able to match
against address ranges. Or Groups. Or any combination thereof.

Support for matching users can take one of several different appearances
in pillar data:

sshd_config:
  matches:
    match_1:
      type:
        User: one_user
      options:
        ChrootDirectory: /ex/%u
    match_2:
      type:
        User:
          - jim
          - bob
          - sally
      options:
        ChrootDirectory: /ex/%u
    match_3:
      type:
        User:
          jim: ~
          bob: ~
          sally: ~
      options:
        ChrootDirectory: /ex/%u

Note the syntax of match_3. By using empty dicts for each user, we can
leverage Salt's pillar mergine. If we use simple lists, we cannot do
this; Salt can't merge simple lists, because it doesn't know what order
they ought to be in.

The fix introduced in 678cc9066c
suppresses the PrintLastLog directive for FreeBSD 10.3.
SSH on FreeBSD 11.0 also does not support PrintLastLog, so this
change suppresses it for any version >= 10.3.

in order to prevent unnecessary changes due to
random ordering of dig results.

Now ssh_config also accepts string-or-list options, for serveral
keywords.

Added a macro to handle multivalue options entered in either string
format or list format (with auto joiner).

Upstream opensshd does not support PAM

Allow user to specify aliased path (with %u)

Added Jinja logic to allow the option to pull the moduli from an online source.

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

This gives us the ability to define system-wide definitions for specific Hosts, and their options.

For example, with this in pillar:

```
# this is the place for host-wide SSH config
ssh_config:
  ...
  Hosts:
    # this simplifies cloning with custom params
    # eg: git clone my-git:foo/bar
    my-git:
      User: git
      HostName: git.example.com
      Port: 2222
```

This would add a section in `/etc/ssh/ssh_config`:

```
Host my-git
    User git
    HostName git.example.com
    Port 2222
```
