Add support to resolve a rename location.

See microsoft/vscode#7340 (comment)

Anyone willing to provide a PR for this to add a textdocument/resolveRenameLocation request to the LSP?

@dbaeumer I have opened microsoft/vscode-languageserver-node#390. It's my first time to implement a new LSP request so I wouldn't be surprised if I've done something wrong.

@dbaeumer Should I bump the version to version 3.11 for textDocument/prepareRename?

[rcjsuen]

@dbaeumer On that note, did you intend to make yesterday's addition of CodeActionOptions version 3.11 or an addition to 3.10? In 7aed39b you made the anchor tag's name version_3_11_0 but you kept the text as 3.10.0.

I opened #551. Dirk, I'll let you handle the versions and so on...

[dbaeumer]

I first thought that I don't need to go to 3.11 for the code action options case. But then later on decided to do so since it adds a feature and is strictly speaking not a bug fix only :-)
