User story

As a Compass user
I want to create a View from an aggregation pipeline
So that I can make sure my data is in the right shape to be used in my application or to create a chart from it.

Acceptance criteria

• When I am in the aggregation pipeline builder and I have written a valid aggregation, I want to be able to save it as a View and give it a name
• When the server is older than 3.4, Save as a View is hidden
• When an aggregation is saved as a View, it immediately appears in the sidebar
• When an aggregation is saved as a View and I open the Database screen, I can see the newly created View
• It is possible to create a View on top of another View
• When I am trying to create a new View with the same name of an existing View, I want to see a meaningful error message
• When the server returns errors (e.g., the user doesn't have the necessary permissions to create a view), Compass needs to handle the errors nicely
• When the View has been created, Compass will open the new View in the main screen (in a new tab, as soon as tabs are available)
