Allow the user to remove some, or all of their history

[boek]

As a user, I want Fenix to delete items from my browsing history so that these items are not discoverable later on this browser.

Acceptance criteria

-I can see a list of URLs I’ve visited in the history section of the Fenix library and delete one site from it.
-I can see a list of every URL I’ve visited in the history section of the Fenix library and delete the entire list at once.
-I can leave the library and return to the library and I will not see the URL
-I do not see this URL when I begin typing an exact match on part of the URL in the awesome bar.
-If I delete this URL from my history while the session window in which I accessed it originally is still active, I will not be able to access the URL using the browser’s back button.

A/C team needs to build this first

Depends on:

• HistoryStorage concept needs a "delete history" interface android-components#1373
• [meta] PlacesAPI History deletion APIs mozilla/application-services#621
