cloud_discovery: Track and persist discovery method

Browse Source 
Adds support for recording the method used to discover the cloud
controller (e.g. DHCP, FLASH, OpenLAN).
The selected method  records the current date and time along
with the discovery method into "/etc/ucentral/discovery.state.json".
The date is stored in epoch format.

Fixed: WIFI-14966
