Prometheus v2 to_yaml add line_width option

[bdeferme]

Pull Request (PR) description

Prometheus v2 to_yaml missing line_width option breaks puppetdb queries by adding new lines.

E.g. using:

  ...

  $_puppetdb_queries = {
    'some_app'  => "inventory { resources { type = 'Package' and title = 'some_app' } and ( ${_environment_query} ) }",
    'node' => "inventory { resources { type = 'Package' and title = 'node_exporter' } and ( ${_environment_query} ) }",
  }

  class { 'prometheus::server':
  ...
    scrape_configs  => [
      {
        'job_name'            => 'some_app',
        'puppetdb_sd_configs' => [
          {
            'include_parameters' => false,
            'port'               => 8161,
            'query'              => $_puppetdb_queries['some_app'],

Without line_width -1, line breaks are added breaking the puppetdb queries.
