This update adds exception handling to catch errors when trying to parse
command output to json. It also removes the dependency on importing json
opting to use the AnsibleModule methods instead
This modifies the return values to make them consistent across all
network command modules. The module now returns stdout, stdout_lines
and failed_conditionals
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.
