Support for AuthPAMService in directories

Use Case

When using BasicAuth with PAM module, the AuthPAMService parameter can be configured:

From https://www.adelton.com/apache/mod_authnz_pam/

<Location /private>
  AuthType Basic
  AuthName "private area"
  AuthBasicProvider PAM
  AuthPAMService tlwiki
  Require valid-user
</Location>

Describe the Solution You Would Like

Implement a auth_pam_service parameter in the directories template.

  apache::vhost { 'example':
    [...],
    directories => [{
        'provider'            => 'location',
        'path'                => '/private',
        'order'               => 'deny,allow',
        'require'             => 'valid-user',
        'auth_name'           => 'private area',
        'auth_type'           => 'basic',
        'auth_basic_provider' => 'PAM',
        'auth_pam_service'    => 'tlwiki',
    }],

Describe Alternatives You've Considered

I don't see an alternative.

Additional Context

I did not find documentation on the official apache website, but Adelton is the official provider for the package in RockyLinux 9 from AppStream repository:

Description  : mod_authnz_pam is a PAM authorization module, supplementing
             : authentication done by other modules, for example mod_auth_kerb; it
             : can also be used as full Basic Authentication provider which runs the
             : [login, password] authentication through the PAM stack.

Start with the directories template and inspect how existing authentication parameters are represented. Add support for the requested auth_pam_service value, then verify that a directory configuration generates the corresponding Apache AuthPAMService directive.
