Add state managers under the key by dash name

[AdityaHegde]

We are seeing issues with stale data from a previously selected dashbaord. This happens when we switch between 2 dashboards that are already opened (this caches data and updates are immediate). Since StateManagersProvider is outside the key the stateManagers.setMetricsViewName is run before the update in metricsViewName propagates to the key and the underlying dashboard components are swapped. There is a brief moment when components will have newer data in state managers but local data is stale. This can be seen in Filters.svelte where we have activeDimensionName.

One quick fix is to add the state managers under the key. Another way is to add safeguard everywhere queries are made using data inside a component, but this is not scalable. We should come up with a good fix in the long run.
