IOS devices only support a single command output which is structured
text. This removes the ability to specify the command output format
when providing complex arguments to the commands
* commands argument now accepts a dict arguments[1]
* waitfor has been renamed to wait_for with an alias to waitfor
* only show commands are allowd when check mode is specified
* config mode is no longer allowed in the command stack
* add argument match with valid values any, all
[1] The commands argument will now accept a dict argument that can
specifiy the output format of the command. To specify a dict argument
use the form of { command: <str>, output: <str>, prompt: <str>,
response: <str> }. Command and output are required arguments. Output
accepts valid values text and json.
The module would raise a KeyError trying to find the save_config key
which is not present in the argument_spec. This was caused by the
check_args() function. Since the ios shared argument spec isn't used
the check_args function is not needed and has been removed.
* using check mode will now block all commands except show commands
* module will no longer allow config mode commands
* check args for unused values and issue warning
