Aleksander Morgado ff8e21b535 api,bearer: new 'apn-type' setting
This new setting allows the user setting up the connection to specify
the purpose of the connection being brought up.

Until now, we would always assume that connections are exclusively
brought up for connecting to the Internet, also limited by the
inability to connect to multiple different APNs at the same time.

But that may really not be true as there may be additional services
that may be accessed through other APNs, like MMS services or even
private networks for companies that have their own APNs on a given
operator (e.g. not that uncommon with banks and connected cars).

The new APN type setting will not change the way the bearer is
connected, but will allow the connection manager to decide what kind
of networking setup the specific connection needs.

This new setting can be provided by the user itself, or implicitly
read from the device if the device stores this information.
