I would like to make P2P_FIND_TIMEOUT large than 30 seconds locally.
Potentially it can be very large value even infinite.
But then connmanctl's 'scan p2p' command will timeout because connman
client has 120 seconds D-Bus reply timeout.
In my opinion it would be better if
1. Make Scan method being asynchronous in the sense it returns upon scan start.
2. Add Scanning property. That is what UI does, for example here
they manage their own m_scanning field.
