The nxos_template module worksw by allowing configurations to be pushed
to Cisco NXOS devices over CLI or NXAPI and templated using the Ansible
Jinja2 template engine
This adds a new module nxos_command that can be used to send arbitrary
commands to NXOS devices. The module includes an argument that allows
the responses to be evaluated and causes the module not to return
control to the playbook until a set of conditions has been met.
