alertmanager default inhibit_rules error

[blupman]

While starting to use alertmanager i noticed the default inhibit_rules cause alertmanager to not start

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 4.10.10
• Ruby: ruby 2.3.3p222
• Distribution: debian/stretch
• Module version: voxpupuli/puppet-prometheus master branch

How to reproduce (e.g Puppet code you use)

  class { '::prometheus::alertmanager':
    version        => '0.14.0',
    install_method => 'url',
    route          => { 'group_by' => [ 'alertname', 'cluster', 'service' ], 'group_wait'=> '30s', 'group_interval'=> '5m', 'repeat_interval'=> '3h', 'receiver'=> 'slack' },
    receivers      => [ { 'name' => 'slack', 'slack_configs'=> [ { 'api_url'=> 'https://hooks.slack.com/services/secret', 'channel' => '#test', 'send_resolved' => true, 'username' => 'username'}] }]
  }

(so, not setting inhibit_rules)

What are you seeing

this causes alertmanager to be installed, but crases after starting, upon investigating i found the error when i started alertmanager by hand.

What behaviour did you expect instead

an empty running alertmanager

Any additional information you'd like to impart

I have created a pull request to generate the same config as params.pp used to make
