Fix Filebeat_oss hardcoded sources

[pearsondavid]

Fix hardcoded sources for wazuh-template.json & filebeat module, the manifest does not allow flexibility for these files to be downloaded from alternative location in air-gapped environments.

https://github.com/wazuh/wazuh-puppet/blob/main/manifests/filebeat_oss.pp#L56

https://github.com/wazuh/wazuh-puppet/blob/main/manifests/filebeat_oss.pp#L63

Can be fixed by adding class parameters and updating resources:

  String $wazuh_filebeat_module_location = "https://packages.wazuh.com/4.x/filebeat/${wazuh_filebeat_module}",
  String $wazuh_filebeat_template_source = "https://raw.githubusercontent.com/wazuh/wazuh/${wazuh_extensions_version}/extensions/elasticsearch/7.x/wazuh-template.json",

  exec { 'cleanup /etc/filebeat/wazuh-template.json':
    path    => ['/usr/bin', '/bin', '/usr/sbin', '/sbin'],
    command => 'rm -f /etc/filebeat/wazuh-template.json',
    onlyif  => 'test -f /etc/filebeat/wazuh-template.json',
    unless  => "curl -s ${$wazuh_filebeat_template_source} | cmp -s '/etc/filebeat/wazuh-template.json'",
  }

  -> file { '/etc/filebeat/wazuh-template.json':
    owner   => 'root',
    group   => 'root',
    mode    => '0440',
    replace => false,  # only copy content when file not exist
    source  => $wazuh_filebeat_template_source,
    notify  => Service['filebeat'],
    require => Package['filebeat'],
  }

  archive { "/tmp/${$wazuh_filebeat_module}":
    ensure       => present,
    source       => $wazuh_filebeat_module_location,
    extract      => true,
    extract_path => '/usr/share/filebeat/module',
    creates      => '/usr/share/filebeat/module/wazuh',
    cleanup      => true,
    notify       => Service['filebeat'],
    require      => Package['filebeat'],
  }
