AU: Don't use network on expensive connection types

Specifically:

- FlimFlam proxy class to query the current network status and find
out if it's expensive.
- Dbus Interface, so dbus can be mocked.
- Libcurl change to redirect the URL if we are on an expensive
connection. This may seem hacky, but the reason I avoided retooling
the whole class is that we may decide that some network usage is
okay on pricy connections. Perhaps it's okay to throttle. So, for
now this is a more minimal change.

BUG=chromium-os:2397
TEST=Unit tests, tested that flimflam proxy works on the device.
