For bearers using STATIC or DHCP IP method, the modem itself is the one
negotiating authentication with the network. The new `allowed-auth' property
allows users to specify which authentication method(s) are allowed to be used.
See the following NetworkManager commit for more reference:

It's pointless to have libmm-common around, just merge it into libmm-glib and
make ModemManager depend on libmm-glib directly. At the end, the non-common
stuff in libmm-glib is really minimal.
Renamed `MMCommonBearerProperties' to `MMBearerProperties', and removed the
`MMBearerProperties' provided in libmm-glib. We'll just use the original one
from libmm-common always.
