no-anonymous-console: every console.log, warn etc should have some identifying string as its first parameter.

I have been on projects where some rookie has put in console.log(a) while debugging something and then it was missed during peer review and some time later the unit tests just start spitting out some random variable value (or just undefined) with no indication of where the console message is coming from. This can be very hard to track down and remove.

Fail

console.log(o)
console.warn(o)
console.error(o)
etc...

Pass

console.log("value of", o)
console.warn(displayName, props)

Auto fix

could add the file name as the first parameter of such console messages.
