MT#17213 Add two-staged puppet run

In some cases puppet should be restarted in order to catch up with
system changes it did itself. For instance if ldap is installed in
puppet session new users won't be available for puppet in the same
session. With this change we have flexibility to run puppet first just
to insall core utils and then do a second normal run.
