Why does each VS Code instance/window needs its own running language server?

And why does it use so much RAM? Each VS Code window uses ~500 MB of RAM just for terraform-ls.exe.

## Versions ### Extension ``` 2.23.0 ``` ### VS Code ``` 1.68.1 …``` ### Operating System ``` Edition Windows 10 Enterprise Version 20H2 Installed on ‎7/‎1/‎2021 OS build 19042.1766 Experience Windows Feature Experience Pack 120.2212.4180.0 ``` ### Terraform Version ``` 1.1.7 ``` ### Steps To Reproduce 1. code path/to/terraform/repository1 2. code path/to/terraform/repository2 3. code path/to/terraform/repository3 4. Verify memory usage ### Expected Behavior 1. terraform-ls.exe shouldn't consume nearly 2 GB RAM for 3 repositories (that aren't all that large) 2. Ideally, the extension could share a single language server across multiple instances of vscode ### Actual Behavior 1. terraform-ls.exe consumes an objectively large amount of RAM 2. Each instance of vscode spins up its own instance of terraform-ls.exe ### Additional context None that seems relevant. ![terraform-ls exe](https://user-images.githubusercontent.com/22461822/176952061-4e3fab43-b076-4a66-9e0b-85329accd075.png)
