Add option to to exclude custom symbols from codelens

[leo-labs]

Fixes #4335

To fix these performance problem I have added an option to exclude additional symbols from codelens which can be used like this in settings.json:

"csharp.referencesCodeLens.filteredSymbols": [
        "MyMethod1",
        "MyMethod2"
    ],

All CLA requirements met.

Thanks for this change! You will also need to define the option in the project.json . I know a lot of people will be happy for this change to get in.

I agree it is time for a new release. I'll start the work to get one together.
