cosmohsieh 64b894f81d Implement getConfig() method to get WifiConfiguration
Make a duplicated function of WifiConfigController.getConfig(). This
function could get a new WifiConfiguration from input AccessPoint or
ScanResult.
Should be removed if there is standard one in framework.

Bug: 120827021
Test: RunSettingsRoboTests
