Rename and fine all references of Typescript's string literal values

[zivni]

Type script string literals allow to have a code such as

//interfaces.d.ts
type Options = "option 1 " | "option 2" 

//file.ts
let myOption: Options = "option 1" // "option 3" will give us an error, right in the IDE.

It would be nice to be able to rename and find all references of a specific value. e.g. find/rename all occurrences of "option 1". Currently we can only find the references of the type itself.
