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`
