Remember which items are collapsed and expanded in the left hand navigation bar

[nwmac]

Internal Reference: SURE-3658

Change behaviour for side navigation so that we don't auto-close the other groups when you click on a nav item within a group.

User can still use the arrow to collapse an expanded group.

We should store the nav state for a cluster to localStorage, so that when the user reloads the UI, they get the expanded state from their previous session. We need to store this per-cluster.

@kwwii ^^ Do we want a preference so the user can turn off the between-session remembering?

The way I see it, instead of a setting with little visibility, I would add a button to collapse the entire navigation, i.e. reset the navigation status as if nothing happened.

Totally agree with Edén here. This should NOT be an extra setting in an alreadey over-loaded list of settings as it will not be easily discoverable. It would be preferable to have proper behaviour without any settings necessary.
