Define usagePolicies API in QNetworkSession

This allows the system to publish usage restrictions to applications
related to the network in use.
Currently there is only one restriction defined:
NoBackgroundTrafficPolicy, which means that non user initiated traffic
should be avoided (e.g. background downloads).
For example this policy could be applied to save battery or data transfer
charges.
