added VRRPGroup (Service) to Router model
better VRRP parser test implementation
Add field IP Range in the client Box.

The BGP range will be the same value.
The BGP field may be hidden if not gives significant information.
Add change button in VRRP box.

Remove activate and deactivate buttons.

Feature/capability routers vrrp parser
Problem with buttons resolved.
Support creation of loopback interfaces.

A loopback interface can now be created, with unit different than 0.
However, there is a limitation and no more than one loopback interface can be configured per router.
This prevents also opennaas to create loopback interfaces for logical routers.

Limitation:
Junos configuration can not be committed when a router has more than one unit in a loopback interface.
http://www.sadikhov.com/forum/index.php?/topic/179436-how-to-add-multiple-loopback-ip-in-one-logical-router/

Trying so will launch following error:
"Multiple loopback interfaces not permitted in master routing instance"

Hence, loopback interfaces cannot be configured if there is already one in the router.
Furthermore, loopback interfaces cannot be added to logicalrouter the same way other interfaces. That is following steps below:
1) configuring interfaces in the physical router (and commit)
2) moving interfaces into logical-system hierarchy (and commit)
As step 1 will fail when committing.
Logical routers inherit chassis capability from their parent.

This way interfaces can be created into logical routers directly (required for loopback interfaces).

Logical routers can not be created within a logical router,
to avoid it some checks have been added to capability implementation.
