Update interface to include sub form prop

[HauklandJ]

Description

Altinn Studio and Apps need a way to communicate to one another that a data type is compatible with sub forms.

Added a property "AllowInSubform" for applicationMetadata AppLogic.

@SandGrainOne Da jeg bygget storage (dotnet build) så kom det inn en migrering-endring, trigget a Post-Build:

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="$(TargetDir)../../../../DbTools/bin/Debug/$(TargetFramework)/DbTools $(TargetDir)../../../Migration" Condition="Exists('$(TargetDir)../../../../DbTools/bin/Debug/$(TargetFramework)/DbTools') or Exists('$(TargetDir)../../../../DbTools/bin/Debug/$(TargetFramework)/DbTools.exe')" />
    <Exec Command="/app_tools/DbTools ./Migration" Condition="Exists('/app_tools/DbTools')" />
  </Target>  

som jeg ikke kan se at har noe med endringen jeg kom med her å gjøre! Hva er dette?
