[Enhancement][UX] Option to set data source as default data source.

[bandinib-amzn]

Is your feature request related to a problem? Please describe.

As a user when there is only one data source created, it still asks me to select data source on dev tool, sample data screens. I want option to set data source as default data source and whenever there is option to select data source, I want that option to be selected by default.

To allow user to assign a “Default” status to one of the connected data sources and manage the preference I propose to implement the UX changes as follows:

1. The first data source that is added to the instance of OpenSearch Dashboards becomes default data source automatically.
2. In the case of multiple data sources connected, and the default data source is removed, the default status is automatically reassigned to the next data source in the list.
3. On the “List connected data sources” (Dashboards management/Data sources) mark the default data source with a badge (OuiBadge) with starFilled icon.

4. On “Create data source connection” page add a checkbox “Set as default data source”. If user selects the checkbox, the newly created data source becomes a default data source instead of the previous default.

5. On the data source details page add a secondary button (OuiButtonEmpty) with starEmpty icon. Clicking on the button sets the default status to the data source. A success toast message is displayed on the page as the default status is reassigned.

6. When a data source is set to default, the secondary button is shown as disabled with the label “Default” and the icon changed to starFilled .
