Draft: Make time range in metrics dashboard behave like in an SPA

What does this MR do?

Part of: #218494 (closed)

Our dashboard would refresh the entire page whenever users would change the time range, with this change we can update the page data.

Please also see #229709 (closed), this MR is an implementation on how to make our dashboards more like a single page application.

Technical Implementation

• Previously, our dashboard would trigger fetching the initial data with the given time range, now that responsibility is passed to the Page that contains it.
• All components that access the store can access the time range same as before.
• The query parameters in the browser bar get updated when time range is updated.

Screenshots

Please note we don't refresh the page:
