With the creation of #471 there will be the ability to load content from a file. The next logical step would be to allow for each file in a folder. The file object returned should include FullName, BaseName, parent dir. Wildcarding would also be helpful. *.xls, *.liquid, etc.

Potentially something like Get_ChildItem from PowerShell.

foreach ($file in Get-ChildItem '$(Pipeline.Workspace)/Infrastructure/Schemas')

Example: I create an integration account and then need to load the Maps and schemas into this integration account. I could see something like

module map 'IntegrationAccount/IntegrationAccountMap.bicep' = [for file in getFiles('integrationAccount/maps'): {  
  scope: resourceGroup()
  name: file.BaseName
  params: {
    integrationAccountName: IntegrationAccount.outputs.name
    mapName: file.BaseName
    filePath: file.FullName
    mapType: 'Liquid'
  }
}]

Today an object with each file path and name listed does the trick, however having this be more dynamic would be excellent. and avoid missing things when they get added.
