Support folder rename in getEditsForFileRename

[mhegazy]

Renaming a folder should cause a rename to all files in the project that are part of the folder.

@mhegazy Has this been pushed back from 2.9.2, or this bug tracking a different feature?

[mhegazy]

there are two parts, 1. changing the folder part of the a file name, that should be working in 2.9.2, but you are still expected to send a file name to the server, 2. sending a folder name directly to the server and the server changing all the files included (that is what this issue is tracking).

Ok. That makes sense. Thank you for the clarification

I'll make sure VS Code is ready for the 2.9.2 part of this
