Remove NetworkStack dependencies on hidden members
- DhcpClient only shares its handler with IpClient, and NetworkMonitor
has its own handler: remove Protocol.BASE_DHCP,
Protocol.BASE_NETWORK_MONITOR
- Remove dependency on Network.netid in NetworkMonitor
- Remove dependency on Sets.newArraySet in DhcpServingParams
- Remove dependency on formatDuration() in DhcpClient
- Replace isMetered() with hasCapability() in NetworkMonitor
- Use WifiManager.isScanAlwaysAvailable instead of reading setting
Test: atest FrameworksNetTests NetworkStackTests
