Huawei save_config should be changed to handle the confirmation

[ktbyers]

Send 'save'

DEBUG:netmiko:read_channel: save
The current configuration will be written to the device.
Are you sure to continue?[Y/N]

Then you will get the abuve message and need to send a "Y" response.

From discussion on Slack, this is the general behavior of Huawei devices (this is for the 'huawei' device_type)

In our OLT MA5600T, there is the command "undo interactive" that suppresses these confirmations. Maybe works in these too.

Another (un)related note: the command "screen-length 0 temporary" does not work in this OLT, but I can get same effect with the command "scroll" and sending another empty command when it asks for the height, effectively setting it to zero.

@eliphaslevy On your note, you would probably have to make a different Netmiko driver for that platform (i.e. for Huawei devices that don't support screen-length 0 temporary).

The fix for this was merged in.
