[FEATURE] Support multiple datasources in the "Roles" tab

[derek-ho]

Is your feature request related to a problem?
Support multiple datasources functionality in the "Roles" tab. This will be a more meaty sub task since this tab contains links to other pages.

Acceptance criteria

• Data source picker shared component is present on the page with a sensible UX
• Data source selections that should be persisted across tabs is accurately persisted
• Selected datasource prior to landing on this page is correctly populated (if applicable), and defaults are selected if not applicable
• Create role button leads to a page with either the cluster picker in read only mode, or writeable mode, so it is clear which datasource the role is being created for.
• View role button leads to the same as above
• Edit role button leads to the same as above
• Duplicate role button leads to the same as above
• Delete role modal makes it clear which datasource the role deletion is happening for (is this p0?)

What solution would you like?
Support multiple datasources in the "Roles" tab.

What alternatives have you considered?
None

Do you have any additional context?
Depends on #1795 to have data source picker available.
