title: Use a glob to target any nested folders with a certain prefix
body: <p>I have a project that has mock json data scattered across different modules. I'm trying to get all the json data to appear in the build using the angular.json config file.</p>
  
  <p>Example list of paths I'm trying to target:</p>
  
  <pre><code>/app/app-mock-data/**
  /feature-module/feature-module-mock-data/** 
  /pages/page-module/page-module-mock-data/**
  /other/other-module/other-module-mock-data/**
  /nested/nested-module/further-nested-module/futher-nested-module-mock-data/**
  </code></pre>
  
  <p>Right now I'm just getting the assets file per module in this project with the angular.json.</p>
  
  <pre><code>// --configuration=mock
  {
    "assets": [
      "src/assets",
      "src/favicon.ico",
      "src/favicon.png",
      {
        "glob": "**/* ",
        "input": "src/app/app-mock-data",
        "output": "/mock-assets/app-mock-data"
      },
      {
        "glob": "**/*",
        "input": "src/app/feature-module/feature-module-mock-data",
        "output": "/mock-assets/feature-module-mock-data"
      },
      {
        "glob": "**/* ",
        "input": "src/app/pages/page-module/page-module-mock-data",
        "output": "/mock-assets/page-module-mock-data"
      },
      {
        "glob": "**/* ",
        "input": "src/app/other/other-module/other-module-mock-data",
        "output": "/mock-assets/other-module-mock-data"
      },
      {
        "glob": "**/* ",
        "input": "src/app/nested/nested-module/further-nested-module/futher-nested-module-mock-data",
        "output": "/mock-assets/futher-nested-module-mock-data"
      }
    ]
  }
  </code></pre>
  
  <p>Is there any glob pattern that allows me to recursively get all items in folders with <code>*-mock-data</code> as a folder prefix?</p>
  
  <pre><code>// hopefully something like this..
  "assets": [
    "src/assets",
    "src/favicon.ico",
    "src/favicon.png",
    {
      "glob": "*-mock-data/**/*",
      "input": "src/app/**/*",
      "output": "/mock-assets"
    }
  ],
  </code></pre>
