Description of problem:

When creating a new network, the check whether the network name is already taken by another network in the same data center is performed case-sensitively (i.e. "mynetwork" and "myNetwork" are considered different names). However, when editing an existing network the check is case-insensitive ("mynetwork" and "myNetwork" are considered the same name).


Version-Release number of selected component (if applicable):


How reproducible:

Always.


Steps to Reproduce:

1. Go to networks main tab.
2. Add network named "mynetwork".
3. Add another network named "myothernetwork".
4. Edit "myothernetwork", try to change name to "myNetwork" --> failure.
5. Add new network named "myNetwork" --> success.
  

Actual results:

Steps (4) and (5) produce different results despite essentially trying to do the same thing.


Expected results:

Either both steps (4) and (5) succeeding or both failing (probably better to be strict and check case-insensitively, meaning that both should fail).
