[Multiple Datasource] Refactor data source menu and clean up data source component configurations

[BionIT]

In #6082, we introduced a data source menu component which acts as a higher level component and rely on the props passed by plugins to determine which component to mount onto the navigation bar.

The components to be rendered are mutually exclusive, and having multiple boolean properties makes it hard to maintain, thus we should switch to a new structure to render the following component:

• DataSourceView
• DataSourceAggregatedView
• DataSourceSelectable
• DataSourceMultiSelectable (to be added)

data source menu component

could developer use those components directly?

between <DataSourceMenu component=DataSourceSelectable> and <DataSourceSelectable />, are there lots of benefit to create a wrap component
