searchbar: Allow to disable key press snooping

The searchbar grabs all key presses in the collection view and use
them to filter the displayed VMs. However, if we need keyboard input
in another widget, the searchbar will prevent it. This commit
adds methods to enable/disable this keyboard snooping when needed.
