Allow exceptions for variable name length tests

[SebastianZ]

People may want to generally disallow short variables, though allow one-character variable names like i for indexes.

Therefore there should be a parameter that allows to define a comma separated list of exceptions when checking variable names.

Not sure I like the idea of a comma-separated list for exceptions. How do other linters, e.g. for JS handle this?

[KamasamaK]

I'm not aware of any other linters that even have rules related to variable name length. The closest thing I've found to accomplish that is one that allows passing a regular expression to validate names against.

Regarding this request in particular, I'm not really sure about it either.

Right or wrong we have the pattern for params with csv. Example from cflint.definition.json:

            {
                "name": "ignoreUpperCaseScopes",
                "value": "CGI,URL"
            },

I would be a fan of moving to a single regex based rule.
