Suggestion: create new rule "new line between class members"

[vyshkant]

I propose to create a new rule that would allow you us track new lines between class members.

Let's call it newline-between-member. The minimum set of properties is: ["never", "always"].

When never is applied, there should not be new lines between class members:

class A {
    private foo: string;
    private bar: number;
    constructor() {
    }
    public doSomething(): void {
        // do something
    }
    public doSomethingElse(): void {
        // do something else
    }
}

Conversely, when always is applied, there should be a new line between class members:

class A {

    private foo: string;

    private bar: number;

    constructor() {
    }

    public doSomething(): void {
        // do something
    }

    public doSomethingElse(): void {
        // do something else
    }
}

I would love to see this rule too.

Also, it should be configurable to apply the rule to which members type, eg. method, property.
