mobile: Add ServiceStatus for retrieving current runtime status of lnd

Browse source 
Used for checking whether lnd is started or not.
ServiceStatus can also be used to determine when lnd has shut down, since
`stopDaemon` returns immediately and does not wait for the gRPC servers
to be fully closed.
