eslint-visitor-keys package

As discussed in yesterday’s TSC Meeting, we need to hammer out the details of the proposed eslint-visitor-keys package. This was proposed to extract and share visitor keys between parsers.

Questions to answer:

1. What does the package exactly contain? Does it contain traversal logic or is just a static object of the default visitor keys (my understanding was the latter but there was some uncertainty during the meeting)?
2. If it contains more than the default visitor keys, should we name is something different?

We can create the repo once we hash this out!

IMO, it should separate about visitor-keys from eslint-traverse. packages such as esrecurse have estraverse as a dependency but it does not use their traversing logic. eslint-scope is same. It’s the sign that estraverse has 2 responsibilities we can separate.

I suppose, although it seems like the visitor keys could be exported by eslint-traverse too.
