Excessive CodeLens Requests

[JustinGrote]

Summary

When a document is open there are codelens requests roughly every 500ms.

Our client current announces it supports refresh in the clientCapabilities, so the expected flow would be:

1. Client Opens Document, requests initial codelens
2. Client makes changes but doesn't request new codelens.
3. If server detects a change that needs a new codelens, it sends a codelens refresh request
4. Client then requests codelens upon notification.

This "polling" of codelens doesn't seem right if refresh is enabled

Looks like @TylerLeonhardt ran into this same thing a while back.
