Network: Minor UI Observations in "Network Configuration" and "Add Adapter" panel

[mesmriti]

1. Navigate to "Host" -> "Network" -> "Network Configuration" section.
   select any configured osa device, and click on actions -> "Set OSA Port". Click on cancel. Interfaces list will be refreshed. It shouldn't refresh interfaces list since there was no action performed.
   Similar observations, when you click on "Actions" -> "Settings" -> "Cancel" or "Add" -> "Add bond"/"Add VLAN" - "Cancel"

2. Navigate to "Host" -> "Network" -> "Network Configuration" section.
   select any configured osa device, and click on actions -> "Set OSA Port".
   in "OSA Port Settings", change the port number,,if '0' then make it '1' or vice versa. "Apply" button will be enabled,, now change back the port number to original value. "Apply" button should be disabled, since there is no change in value. But its not disabled.

3. Navigate to "Host" -> "Network" -> "Network Configuration" section.
   select any configured osa device, and click on actions -> "Set OSA Port". change the port number value in "OSA Port Settings" and click on apply.
   A pop up is shown with warning message -- "Do you want to change the OSA port configuration of the interface enccw0.0.1530 to 0.
   Please confirm !!!"

since changing osa port affects network connectivity(device is restarted), the warning message --
"Do you want to change the OSA port configuration of the interface enccw0.0.1530 to 0?
This may affect network connectivity!"
--is more relevant than the current message.

4. Navigate to "Host" -> "Network" -> "Network Configuration" section. click on "Add" -> "Add Adapter".
   select any device from "Offline Devices" list,,click on "Enable"
   pop-up appears for "OSA Port" selection.

the "note" in the pop-up doesn't get required attention from user since looks kind of hidden between "i" symbol and '*'.

5. Navigate to "Host" -> "Network" -> "Network Configuration" section. click on "Add" -> "Add Adapter".
   select any device from "Offline Devices" list,,click on "Enable", select osa port and click on "Apply".

The "loading" message cannot be seen properly, and offline devices list should be completely faded highlighting 'loading' message ,,also "Finish" button should be disabled.
