Use FrontMatter for discovery

Imho this would be no win in practice. Frontmatter is a super tool to store a few lines closely related to the main content.
But in this case a long list of metadata would only clutter the template.

Or put the othdr way rounde: Yes we can store metadata in the template. And while we're at it, include css, js, and more, and advance to single-file componente. And... NO...

This is something that we considered in our discussions. However we decided against it for the following reasons:

• It is another new foreign concept on top of the components that gives us little benefit.
• It locks us to one single template. While we might want to have alternate templates in the future for component variants.

Unless there is an obvious benefit to this, I would lean towards keeping the familiar *.component.yml.

As andipost does not chime in, closing.
