* Do not hardcode /etc/postfix

In order to bring support for FreeBSD, do not use the hardcoded
/etc/postfix path for the directory containing Postfix configuration:
FreeBSD ports are installed with a /usr/local/ prefix (by default) so
the configuration files on FreeBSD are stored in the
/usr/local/etc/postfix directory.

* Add support for FreeBSD

* Make it possible to tune the "root" group

FreeBSD does not have a "root" group.  The corresponding group is named
"wheel".

Allow to setup a custom "root_group", and adjust FreeBSD configuration
to set it to "wheel".

* Adjust the test suite so that it pass on FreeBSD

* Do not depend on $postfix::* before including postfix

Some resources parameters depend on the value of variable from the
postfix class.  Ensure these values are substitued only after including
postfix.

* Move default values from hiera to init.pp

These values are system-dependent, but this helps seeing the usual
default value when gen...

* Make rubocop happy

* Make puppet-lint happy

* Fix resetting bundler_args

The default value was not cleared, resulting in prerequisites not being
installed before running acceptance tests.

Fixes an issue where if a postfix map $ensure is 'absent' the postmap exec resource causes puppet runs to fail.

* Convert to PDK

* Add beaker

* Adjust Gemfile and .travis.yml

* Rename tests dir into examples

* Deactivate rubocop for now

* Remove rspec config

* Rubocop autocorrect

* Fix Lint/ParenthesesAsGroupedExpression

* rubocop autocorrect

* Exclude examples tagged with excl

* Move params validation to corresponding class: We only need to valide the
params when they need to be set / are actually used. Since Puppet 4.6 or 4.7,
stdlib's validate_string function doesn't accept undef anymore, so this has
to be changed.

* Remove specific error checking in specs: types checking validate_* functions
have different error messages depending on the version the stdlib module, the
version of puppet, maybe the version of ruby, the phase of the Moon... who knows.

* Add a map define to create postfix maps

It is similar to existing hash define, but this define can create maps
of any type, not just hash.

* Refactor postfix::hash to avoid duplicate code

postfix::hash uses now the new postfix::map to create the hash
