     bitbake: toaster: Add layer details page feature

     This commit adds the layer details page which shows the metadata 
for the
     layer such as layer description, machines associated with the layer 
as well
     as the targets provided.
     If the layer is an imported layer this page also allows you to update
     the layer's configuration.
     From this page you can add/remove the layer from the current project
