    Add support for PlantUML diagrams in Asciidoc. · f986b4c4
    Horacio Sanson authored
    This MR enables rendering of PlantUML diagrams in Asciidoc documents. To add a
    PlantUML diagram all we need is to include a plantuml block like:
    
    ```
    [plantuml, id="myDiagram", width="100px", height="100px"]
    --
    bob -> alice : ping
    alice -> bob : pong
    --
    ```
    
    The plantuml block is substituted by an HTML img element with *src* pointing to
    an external PlantUML server.
    
    This MR also add a PlantUML integration section to the Administrator -> Settings
    page to configure the PlantUML rendering service and to enable/disable it.
    
    Closes: #17603
