Reuse component for Collector documentation

[kickoke]

The file _config.mdx is a component for the "Configuration" section in the collectors documentation.

The goal is to pass the file name of the configuration file into a variable, so the component can render the same information but with a changing filename.

Currently, the reuse doesn't work because of the following error in _config.mdx.

Module parse failed: Unexpected token (3:3)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| export const pluginFile = "Default Value";
|

To edit the <>{props.pluginFile}</> configuration file:

| 1. Navigate to the Netdata config directory.

Hi there, I look into this over the weekend.

In the latest commit you can see how this method could work (don't pay attention on the paths, just the implementation), unfortunately this functionality included in
docusaurus v2.0.0-beta.4 (https://github.com/facebook/docusaurus/releases/tag/v2.0.0-beta.4) but in this version (and the later on) there is this facebook/docusaurus#6072 issue that we must examine.

So we pause this effort for now.

Next steps:

• update docusaurus in a newer version (we need this for other reasons also)
• check if this implementation works

@tkatsoulas Just to document the current state:

You've tested the _collector_config.mdx file on 2.0.0beta15, right?
The outcome was that the reuse in the code block and the list item didn't work.

Let's test the _config.mdx file because this has the component markup (<>{props.pluginFile}</>) in all instances and maybe it works then.

yes

You can check the check_reuse_mdx_in_beta_15 branch, the issue still remains
