Modules should allow specifying directory and auto-load all files with-in

[Pavaningithub]

Request

When we are working with module, filename in module.file allows only filename.

Say for example if we configure a module with multiple river files, as show in the screenshot, when we call the module directory instead of file, we get below error.

module.file "metrics_logs_config" {
        filename = "/etc/agent/modules/"

        arguments {
                argument_name = {
...
        }
        }
}

Error:

/etc/agent/module.river:1:1: Failed to build component: building component: failed to read file: read /etc/agent/modules/: is a directory

As of now we can specify only a single file in module block. it would be great we can specify the module directory and flow mode auto load all files.

Use case

This helps in modularize the code and handle the components in multiple files.
