Update: Uniform messages for the rules in "complexity" section

[IgorNovozhilov]

What is the purpose of this pull request? (put an "X" next to item)

• Changes an existing rule (template)

What rule do you want to change?

It is proposed to unify the content of messages from the category "complexity". And make them more informative.

Does this change cause the rule to produce more or fewer warnings?

no changed

How will the change be implemented? (New option, new default behavior, etc.)?

• Changing the message template in exports.meta.messages
• Changing data in a context.report method call

Please provide some example code that this change will affect:

function test(a) {
  // Comment qwerty qwerty qwerty qwerty
  if (a) {
    if (a) {
      console.log('qwerty');
    }
    a(function() {
      onsole.log('qwerty qwerty');
    })
    a++;a++;a++
    if (a) a(); else a();
  }
}
 
test(a);test(a);

class a {
  
}

class b {
  
}

rules config

  "rules": {
    "complexity": ["warn", 1],
    "max-depth": ["warn", 1],
    "max-len": ["warn", { "code": 30, "comments": 36 }],
    "max-lines": ["warn", 7],
    "max-lines-per-function": ["warn", 5],
    "max-nested-callbacks": ["warn", 0],
    "max-params": ["warn", 0],
    "max-statements": ["warn", 2],
    "max-statements-per-line": ["warn", { "max": 1 }],
    "max-classes-per-file": ["warn", 1]
  }

What does the rule currently do for this code?

What will the rule do after it's changed?

What changes did you make? (Give an overview)

complexity, max-depth

• Added maximum allowed rule value

max-len, max-classes-per-file

• Added actually rule value

max-lines, max-lines-per-function

• Uniforming a rule message

Is there anything you'd like reviewers to focus on?

Also I want to change the messages for the rules: max-classes-per-file, max-statements-per-line, and possibly other similar rules that use numeric metrics. Are there any other such rules?
