Add ability to clear recently viewed

Describe the feature:
The 'Recently viewed' section of the left hand nav is a handy way to navigate Kibana and reduce navigation efforts for our users. That said, the current use of local storage (while we await a proper personalization solution) present some quirks if/when a user signs in using multiple accounts or if users were to share a computer/browser.

Describe a specific use case for the feature:
One way we could partially mitigate this situation in the short term would be to provide a 'Clear recents' link or button in that section of the nav.

More can certainly be done, but this feels like a nice improvement that will remain useful even into the future once a personalization backend is available.

I think the best alternative would be have another saved object - per elastic user? And kibana can use the add/remove api internally to fetch it

That way, if a computer is shared, those errors are removed. Additionally, recent views would roam with the user, instead of being browser/pc specific.
