Public bug reported:

As we are adding more logic to panels for hiding or showing them
depending on what is available in other services, we will inevitably
have to call out to those other services' APIs to check things. Since
the main menu with the panel list is displayed practically on every
page, those calls would be made on almost every single request to
Horizon. This would slow things considerably, and is also very
inconvenient to mock in tests.

The solution to this is to introduce a caching mechanism, which would
keep the list of dashboards and panels to be displayed in the session's
cache, and which could be conveniently mocked as a whole in tests.
