Check PAN-OS Firewall Readiness

---
# check_ready.yml - Checks to see if a firewall is ready via 'show chassis-ready' command.
#
# Description
# ===========
#
# Uses the 'show chassis-ready' op command to see if a PAN-OS firewall is ready.  This playbook uses the Ansible
# 'until' and 'retries' keywords to retry the command until successful.
#
# This playbook requires connection details for the device to be specified in the variables 'ip_address', 'username',
# and 'password'.  These may be defined as host variables (see `host_vars/firewall.yml` for an example) or
# extra vars.
