Description of problem:

Since external network provider feature was introduced, there is no way of telling which network is required and which is not in Setup Host Networks dialog. (see screenshot)

However there is a vertical space which separates required/non required networks (see screenshot)

At the moment only way of knowing wether the network is required or non-required is to go via 

Networks -> your network -> clusters -> Manage Network
or
Clusters -> your cluster -> Logical Networks -> Manage Networks

which is inconvenient

Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Manager Version: 3.3.0-0.32.beta1.el6ev 

How reproducible:
100%

Steps to Reproduce:
1.Create 1 non-required network on cluster and 1 required network on cluster
2.Hosts -> your host -> network interfaces -> Setup Host Networks
3.

Actual results:
Since external network provider feature was introduced, there is no way of telling which network is required and which is not in Setup Host Networks dialog. (see screenshot)

However there is a vertical space which separates required/non required networks (see screenshot)

Expected results:
1) Add description text above required/non required section
or
2) add add required flag into tooltip which appears on hovering mouse over network
