When creating a cloud-init user data script, one may want to use the write-files directive to write out Foreman snippets, which would need to be indented. I'd like to add a helper called indent so I can do something like this:

#cloud-config
some_directive: true
foo: bar
write_files:
- path: /root/freeipa.sh
  permissions: '0755'
  content: |
<%  
  indent 4 do
    snippet "freeipa-register" 
  end
%>
