ansible yaml for doing os-upgrades of ex2200 (may not always work all the way).

This relies on having credentials/login in ansible under the label 'ansiblefw'
and an inventory from which you can look up targets

The playbook will install the os, wait for the device to reboot, and do a 
snapshot and rescue config afterwards.

With ex2200, we do not always detect that the reboot command goes through, in which
case the script considers the device to have failed. We must then do the snapshot/rescue 
config manually, or with another playbook.

Fire it like this:

ansible-playbook this.yaml -e victims=hostname1:hostname2:hostname3:and:so:on
