Support scrape_config_files option

[willfurnell]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7.28.0
• Ruby: ruby 2.0.0p648
• Distribution: CentOS 7 server, Rocky 9 client
• Module version: 13.4.0

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

class profile::prometheus_server {
  class { 'prometheus::server':
    scrape_config_files => '/etc/prometheus/scrape_configs/*.yml',
  }
}

What are you seeing

I cannot use the new config option scrape_config_files added by this issue/PR prometheus/prometheus#12019 prometheus/prometheus#8543. It was added in Prometheus version 2.43.0

What behaviour did you expect instead

To be able to use this config option.

Output log

Any additional information you'd like to impart

It would be nice if this is supported by the module.
As workaround you can add a custom config template. I copied the original (modules/prometheus/templates/prometheus.yaml.erb) and added the line 'scrape_config_files'=>['/etc/prometheus/scrape-config.d/*.yaml', '/etc/prometheus/scrape-config.d/*.yml'] and
called class prometheus::server with config_template => 'path/to/new/template', but a default and more flexible way would be nice.

@willfurnell, @reini-1 interested in providing a pull request to implement this?

I didn't see this issue. #782 tries to implement this.

Hi there!

As far as I know there has been no release since #782 has been merged, hence this parameter is still not available, at least if you use the module from the Puppet Forge.
Merge occured on July 11, but last release of this module (0.15.0) is from June 13.

If a new release could be done, we could mark this issue as done!
For now, I'll simply get the module from the master branch.

Thanks in advance for anyone that can look into this !

@redat00 I try to make a release soon.
