Add refactoring option to convert string concatenation to template literals

[alex-kinokon]

Consider adding the refactoring option to turn a string concatenation

console.log("My name is " + firstName + " " + lastName + ".");

to ES2015 template literals:

console.log(`My name is ${firstName} ${lastName}.`);
