Extend "jsx-boolean-value" to support optional "ignore" list

[mehdivk]

It would be great if we could configure jsx-boolean-value to ignore a list of props.

Example

{
  'react/jsx-boolean-value': ['error', 'never', { ignore: ['value']}]
}

This allows the following expression to be valid

<Toggle value={true} />

And if you wonder why I'm not using a prop like toggled instead of value, it's because we want to have a set of components that support the same prop.

I'm more than happy to support the idea with a PR.

why wouldn't you want to do <Toggle value />?

Good question. I think <Toggle value /> has some readability issues. For props that ends with ed (E.g. checked, toggled, disabled etc) it makes sense to drop {true} but not for something like value.

It sounds like then you wouldn't want "ignore", you'd instead want a setting that enforced "always" for that prop.

Yes, I want to use a mix of always and never in my project.

This should cause lint error

<Toggle toggled={true} />

but this should pass the linting

<CheckBox value={true} />

and this should cause lint error

<CheckBox value />

Although I don't personally agree with that style, an option to the rule to allow this works.

What about, only with "always", a "never" option - and only with "never", an "always" option? Both options would be a unique array of prop names.
