Pinned agent management refactor

[jbiset]

Description

A service needs to be created to manage the pinned agent that replaces the current mechanism. This service should update the application state and URL with respect to the pinned agent. Additionally, this service must provide the methods to get whether an agent is pinned, get pinned agent data, and pin an agent. Finally, the corresponding behavior must be added to DataSource to update the filters when changing the pinned agent through the pinned agent management service.
