Fuel UI does not allow to configure non-default public network range

[Mikhail Chernik]

In 9.0-mitaka when Public network CIDR is changed, Fuel UI does not allow to save changes.

Steps to reproduce:
1. On Networks configuration tab change Public network CIDR for default group (e.g. change 172.16.0.0./24 to 172.16.1.0/24)
2. Update IP Range and gateway values according to new CIDR
3. Try to update Floating network range on Neutron L3 page according to new CIDR

Expected result:
Fuel UI is aware that values should be changed on two pages, so it either allows to save changes despite (temp) misconfiguration, or remember not saved changes for all network settings.

Actual result:
Save button is disabled, after navigating to Neutron L3 page changes to Public network are reset

Workaround:
Open Fuel UI in new tab, configure Floating IP range, then configure Public network and save changes (or configure network via CLI)

Verified on fuel-9.0-129-2016-03-29_08-00-00.iso
Verification scenario:
1. On Networks configuration tab change Public network CIDR for default group (e.g. change 172.16.0.0./24 to 172.16.1.0/24)
Step Result: Save button is disabled, because IP Range and Gateway must match new CIDR
2. Update IP Range and gateway values according to new CIDR
Step Result: Save button is disabled because Neutron L3 Tab mustbe updated with correct values
3. Try to update Floating network range on Neutron L3 page according to new CIDR
Step Result: Floating network range can be updated, Save button becomes enabled in current place after user has provided correct range
4. Return to Default page
Step Result: all values look as at the end of Step#2 , Save button is enabled
5. Return to Step#3 and inspect Floating range
Step Result: all values are still saved , Save button is enabled too
After navigating to other pages changes to Public network are saved and can be applied using Save button
