One Apex LSP instance for multiple VSCode Windows

Is your feature request related to a problem? Please describe.
Every time when new VSCode WIndow is opened a new Apex LSP instance is tarted. In SI world we usually switch between projects and I usually I have 3-5 project opened. If I open 5 projects in different VSCode windows I end up in 5 Apex LSP instances working in the background and only one of them can be active. It would be great if multiple VSCode instances can talk to the same Apex LSP server.
