awful.tag: Add "volatile" property 

Useful when using dynamic tags. The tags will be closed once
it is empty. This was part of Tyrannical for many years, but is
generally useful for other workflows too.

   local t = awful.tag.add("my_tag",{volatile=true, screen=2})
   awful.spawn("ayapp", {tag=t})
