[BUG] smartap-cfg throws an exception when trying to configure the device under certain conditions

[muurk]

Description

The smartap-cfg application does not gracefully handle conditions where the smartap device does not respond to HTTP requests

Steps to Reproduce

1. Run the smartap-cfg utility
2. Allow it to scan the network
3. Select the smartap unit to configure, press enter
4. If the smartap device fails to respond to the HTTP request for configuration data, smartap-cfg will throw an error when the HTTP request times out

Expected Behavior

smartap-cfg should display a message to the user indicating a request has been made and we're waiting for a response.

If the smartap device responds, the user is taken to the configuration interface.

If the smartap device does not respond, the user should be shown a message to explain the device is unavailable and should be power cycled before trying again.
