Add nm-dhcp-ib-interfaces element

Browse Source 
Currently, NetworkManager can't automatically create default
connection profiles for InfiniBand interfaces.

So, as a workaround, we are adding nm-dhcp-ib-interfaces element to
install NetworkManager-system-connections-infiniband.nmconnection
to NetworkManager to create a wildcard InfiniBand connection profile.

The content of NetworkManager-system-connections-infiniband.nmconnection
is generated by running this command:
`nmcli --offline connection add type infiniband connection.multi-connect multiple`

=====================
Add InfiniBand connection profile to run DHCP for InfiniBand interfaces
As it's not implemented yet to create default connection profiles for
InfiniBand interfaces in NetworkManager, we are providing a wildcard
InfiniBand connection profile to allow it to run DHCP for InfiniBand
interfaces.
