Clean up .fixtures.yml style

[ekohl]

Drops the Puppet < 6 compatibility, which is no longer needed. It also applies a consistent formatting.

I ran bundle exec rake spec_prep and then tried running the acceptance tests. I'm seeing:

  Error: /Stage[main]/Candlepin::Config/Concat[/etc/candlepin/candlepin.conf]/Concat_file[/etc/candlepin/candlepin.conf]: Failed to generate additional resources using 'eval_generate': undefined method `filter_map' for #<Array:0x0000000003ddf038>

and later

  Error: /Stage[main]/Postgresql::Server::Config/Postgresql::Server::Instance::Config[main]/Concat[/var/lib/pgsql/data/pg_hba.conf]/Concat_file[/var/lib/pgsql/data/pg_hba.conf]: Failed to generate additional resources using 'eval_generate': undefined method `filter_map' for #<Array:0x00000000045a2248>
  Did you mean?  flat_map
  Error: /Stage[main]/Postgresql::Server::Config/Postgresql::Server::Instance::Config[main]/Concat[/var/lib/pgsql/data/pg_ident.conf]/Concat_file[/var/lib/pgsql/data/pg_ident.conf]: Failed to generate additional resources using 'eval_generate': undefined method `filter_map' for #<Array:0x00000000047934d0>

This seems due to the same underlying issue as puppetlabs/puppetlabs-concat#771

Can you pin it so that we are using a compatible version?

Can you pin it so that we are using a compatible version?

I've been thinking of going the other direction: drop Puppet 6 and Ruby < 2.7. It's surprising to me that the Ruby 2.5 unit tests pass.

I do wonder why the Puppet 7 tests are also failing.

@ekohl how can I set the puppet version to use when testing with https://github.com/voxpupuli/beaker-vagrant ?

[ekohl]

Oh yes, we should really update this line:
https://github.com/voxpupuli/voxpupuli-acceptance/blob/e1f5ad4eaedf10acc21b47c26045afe33c5c9c42/lib/voxpupuli/acceptance/spec_helper_acceptance.rb#L5

So set the env var BEAKER_PUPPET_COLLECTION to puppet7 and that should work.

I think this is safe to merge despite the Puppet 6 failure
