Vlad Zahorodnii 97cf90269a Start accepting client connections after creating workspace
Sub-classes of the AbstractClient class need a valid instance of the
Workspace class to function as desired. We should not create xdg-shell
clients until the workspace is created.

/**
* The WaylandXdgShellIntegration class is a factory class for xdg-shell clients.
*
* The xdg-shell protocol defines two surface roles - xdg_toplevel and xdg_popup. On the
* compositor side, those roles are represented by XdgToplevelClient and XdgPopupClient,
* respectively.
*
* WaylandXdgShellIntegration monitors for new xdg_toplevel and xdg_popup objects. If it
* detects one, it will create an XdgToplevelClient or XdgPopupClient based on the current
* surface role of the underlying xdg_surface object.
