On stable/Newton in the Network Topology's Graph view, "Toggle Network Collapse" Toggles back automaticaly

[Yves-Gwenael Bourhis]

Steps to reproduce:
===================

On stable/newton with FireFox 52.0:
* Go to the Network Topology view
* select the "Graph" tab
* If the view is not collapsed, click on "Toggle Network Collapse"
* Click on "Toggle Network Collapse" to uncollapse the view (see all instances).

Issue:
======

After following the above steps, wait a few seconds, the topology view Collapses automatically (and hides all instances).
If one clicks again on "Toggle Network Collapse" to view all instances, after a few seconds it toggles back by itself.

    Fixes toggle behavior in Network Topology graphs

    Changes the buttons (Toggle Labels and Toggle Network Collapse)
     in the network topology graph view into bootstrap styled checkboxes
    (the buttons should now operate as on/off) and modifies the relevant
    js code to prevent random un-toggeling on data loading. Additionally,
    the states for each button should now be respected on page refresh.
