Markdown Diagrams on web pages nga netANS dev

Render PlantUML, Mermaid and others graph/diagrams on markdown preview web-pages. For example, PlantUML syntax on a scm web interface with a markdown preview (Bitbucket, Github...) will be interpreted and the graphs will be displayed directly on the web page without any actions needed by the user. By default the extension sends diagrams to the free public cloud instance https://kroki.io to interpret the syntax to a diagram.
